       | Interesting study, but the effects on earnings weren't as extreme
       | as the headline led me to believe:
       | 
       | > Stated differently, being the descendants of the Bernardi
       | family (at the 90th percentile of earnings distribution in 1427)
       | instead of the Grasso family (10th percentile of the same
       | distribution) would entail a 5% increase in earnings among
       | current taxpayers (after adjusting for age and gender).
       | 
       | A 5% difference in earnings between descendants of a 90th
       | percentile family and a 10th percentile family may be
       | statistically significant, but it's still only 5%. A 5%
       | difference in earnings isn't going to move someone from lower
       | class to upper-middle class lifestyle.
       | 
       | The authors found that some of this effect was due to certain
       | families that tended toward elite professions like doctors and
       | lawyers. I suppose we could make an argument for eliminating
       | legacy preference in university admissions, but I'm sure some
       | families would still bias toward certain professions in the
       | interest of following in their parents' footsteps.

         | On the contrary I believe. If you really factor in social
         | momentum a name and association with the city can carry, it may
         | be neutral. Perhaps some intelligence in inheritable and you
         | got your answer.
         | 
         | But even over such long times wealth can be transfered. Don't
         | know how many can trace back their lineage to the Medici, but

         | If I'm reading that right, that's a 5% _earnings_ boost, not a

         | 
         | Reasonable wealth appreciation on a 5% "bonus" check / year is
         | an incredible amount of wealth.
         | 
         | Just for reference, investing 1 <currency>/year for 60 years at
         | 6% returns is 533 <currencies>. A 5% boost might be an extra
         | 10,000 USD for a high earner (like a 90th percentile earner).
         | That's 5,330,000 USD earned in a lifetime just from investing
         | that family name bonus. That kind of money would buy your
         | grand-kids a nice college education.
         | 
         | That wealth has probably enabled a lot, including the increased
         | opportunities that gives every single one of their descendants
         | a 5% boost in income.

             | The above math indicates that one generation with this 5%

             | 
             | It also suggests that looking at wages is a misleading
             | statistic, as wages do not typically make up the majority
             | of money that a wealthy individual would gain in a given
             | year.

         | Why would we want to do anything to change it? I'm having
         | trouble expressing this idea so maybe it's not clear but you
         | want to change who ends up wealthy from one random person to
         | another random person? Whoever it is is still just human like
         | the other one. It's already a complete lottery which family
         | somebody will be born into. As long as you accept that some
         | individuals will end up advantaged over others, why does it
         | matter which ones they are? The result will still be "high
         | income earners earn higher income than low income earners".

           | I think that instead of framing it as fairness--which seems
           | to agitate those who were born with monetary advantages, this
           | conversation should be re-framed to focus on societal
           | efficiency.
           | 
           | It is inefficient to shoehorn people to the top because their
           | parents were at the top. The people at the top should be our
           | highest achievers and not our decent achievers who were born
           | with rich parents.
           | 
           | The way our society is structured we will find ourselves much
           | better off in a few generations if we can devise a system
           | where each persons potential is given a proper environment to
           | flourish and where each high potential person is given a
           | carrot to chase that isn't unachievable.
           | 
           | Edit:
           | 
           | Speaking of carrots to chase. It's looking more and more like
           | the wealth of millennials(and I suppose zoomers?) long term
           | will be very very determined by their inheritance(if they are
           | so lucky to have one lol) and less so by their hard work in
           | life.
           | 
           | This is likely the cause of the number of people under 40 who
           | seem to be "opting out". It's very difficult to get to the
           | supposed goal unless you are a high achiever. The carrot is
           | very much too far away and this is another societal
           | inefficiency. We would have a much more dedicated workforce
           | if we made it possible to get "carrots".

             | situation by playing by the rules.
             | 
             | If the people at the top try to just promote defeatism to
             | talk people out of challenging their place, they risk
             | something quite different: if you believe putting more
             | effort towards playing the game won't change your
             | situation, you start looking at alternatives like crime or
             | revolution. The random people who were born rich don't
             | deserve it any more than you, so let's replace them with
             | us. A system that isn't based on violence or the threat of
             | violence can only work if people believe it actually does
             | give them opportunity.

       | 
       | I wouldn't be surprised if white supremacists started using
       | studies like these to "prove" that since Jews stayed wealthy over
       | multiple generations, they must be conspiring to cheat the
       | gentiles.
