Tribal human
People used to group together into clans and tribes for millennia, mostly for shared resources and protection against dangerous animals, humans and times. Over time such organisations got less and less important in our daily lives, and depending on culture and historical circumstances, has often disappeared all together.
Clans used to be couple of extended families grouped together, each family having several dozen members. Families might have shared ancestry in the past, maybe it was just bigger extended family split into several families. Or maybe some families could have formed a clan by intermarriage.
And tribe used to be several clans sharing same culture, ancestry, religion. After tribe grew too big, more than thousand members, it could also split in several related entities.
Modern nation states, after hundreds of years of feudal oppression and then few more centuries of industrialisation have pretty much destroyed those entities. Now state is protecting us, each of us can make living good enough for food (more often, than not) and there is not much need to bond together to create a hunting party.
So, we are all by ourselves, with nearest family close by and extended family further than 1st cousins stays pretty much unknown.
Not!
During recent times, word "tribalism" has often been heard with negative connotation. Like in Iraq or Afghanistan, some tribes fight against rule of government, or that there are deadly blood feuds between tribes, or that corruption and nepotism is in the record highs due to clans sticking to their own.
Somehow, in Europe, only places where I have heard clans mentioned, are Scotland, with its harmless rituals, and Italian Mafia clans, with their not so harmless line of work. In England, Sweden, Austria or Switzerland there are no such thing, yet "tribalism" is still considered something evil. Why? I am not sure - it might be because of old rivalry between nation state and its interests, and interests of tribes and clans. Regardless, one can hardly imagine such issues in modern Frankfurt or Krakow.
Yet people still like the idea. It provides warm feeling of belonging to the group, being protected, not being alone against the universe. I have always wanted to be part of the group. During teenage years in school, during university, when I set to conquer internet for first time, when I joined club of interests for first time. Lots of love for bonding myself with others.
Also, I have noticed that when reading Fantasy or Science fiction books, I always like and enjoy a lot that heroes have clans and structures they protect until their last breath, swear allegiance to and act all honourably no matter what happens.
Something just draws me to that, even if such set-up is impractical, not easy to set up, and bound to create hard to solve problems.
Idea for modern society
So, lot of reasons why we might love clans and lots of fair reasons of why we do not have any.
Could we use this concept to our advantage, while keeping all the potential issues locked away for good?
Yes - why not. There are lot of times when we could use helping hand and feeling of belonging to a group, without that deteriorating into feuding, bribery and general rot. And sometimes government also could use the fact that there are groups of people who stick together.
And no, I am not talking about collective punishments there - that would be very very bad, and such government would not live too long. My idea is exactly opposite, but with the same effects.
Lets create collective incentives, based on clan. Clan could be 3-4 extended families tied together, either randomly by government, or by their own choice, or by some clever mix of the both, that makes things nice, clean and even. In any way, if we have group of people, not bigger than two hundred, I would say - it has to be comprehensible and has to feel real for average person, then we as a government, can set some quite easily achievable targets for whole group and then reward the clan with some tax break or another.
For example, it is very important for our collective safety, that everyone has been vaccinated for all the preventable diseases - even small percentage of population who has not, can create huge risk for everyone. So, we can set a target for a clan, that if over 97% of clan members of appropriate age have been vaccinated, then clan receives discount on family doctor fees for next five years. Such a scheme might actually pay for itself, as vaccinated people would have to visit doctor less often anyway. And collective pressure - imagine if 20% of your clan are old ladies for whom such fees are very important - will shoot vaccination levels sky-high with no extra effort from government. All the money booked for 'social advertising' could be spent elsewhere.
Let me give you several more ideas. For example, education, if at least 90% of clan who are of age from 19 to 65 have finished high school, then everyone trying to enroll into state university, will have slightly better chance of enrolling. Or slightly smaller school fee. Or a bit better deal when getting student loan.
Or, for example, if everyone of age from 18 to 65, are either in school/university, has a job (including being businessman and paying salary to themselves) or has registered in state unemployment agency and shows up for trainings/job interviews/etc - then all the clan pensioners get 105% pension and all the toddlers have slightly better chance to get into state kindergartens. Imagine peer pressure to pay taxes, seek job and keep thyself in school!
And of course, if that was hard to achieve in previous days and ages, then now, in 21st century, there can be simple page in internet, connected to your favourite social network, that would show achievable targets and (personalised) benefits that you as a member of a clan would receive, if achieved. And list of people who has or has not performed/complied with said target.
And of course, if you are loner, like to live in the forest and hate everyone - you can opt out of such schemes. Of course, if there are no taxes incoming from you, then state might get more suspicious of you than others.
Bigbrotheresque issues of course are valid concern. And state should not invent more information to gather from people, and should not increase pressure in any other ways and of course - never should do collective punishment. Government already has tons of targets on what consensus is there - those are then prime candidates for usage within this paradigm. And yes, state most likely already has all the data mentioned above - it just needs to be put together and used appropriately.
