You shuld not be liable for the past 200 year old pensioners pensions, but you have to pay for them. It is determined by the government, it is very powerful.
But most of these young people wont enjoy pensions:
Either they will die before pension (global meltdown, starvation , WW3)
Or there will be no pension funds by then.
Either way we look for a bad future ahead.
unless there is a real revolution and Bitcoin is part of it.
The revolution changes the way wealth is distributed and that is usually very violent but also interesting time (if you are lucky enough to survive).
So I would say, interesting times are ahead of us!
