Probably the biggest thing you could do is make wealth use it or lose it. No passing down generational wealth anymore. Tax estates at 100%. A reasonable exclusion for "regular people" but no cut outs for spoilt kids and grandkids and their pets. No hiding in trusts. It gets one inheritance of a single family home to a single dependent or spouse and the entireity is auctioned off and sold. No palacial estates or farking castles with 37 car garages and a theme park,a single high median income single family home.
Spend it before you die or the public gets all of it. If they don't have a qualifying home, they will be provided enough funds from the sale to acquire them one.
There are a bunch of issues with this idea.
Number one, from a libertarian perspective I simply don’t believe “the public” (the government) deserves it.
Number two, in the case of something like Tesla, the government will almost certainly destroy it. They can’t run it. It will be worthless in a few years and they will have destroyed hundreds of billions of dollars of value and wealth.
Number three, as an employee of a private, single-man-owned company with 20,000+ workers and does about $7-8B of revenue a year in a critical industry…what happens to us? Just shut it down? Government runs it into oblivion? 20,000+ of us lose our jobs because a dude died?
People like to rail against the Paris Hiltons of the world and get all indignant that she’s a member of the lucky sperm club and they are not, but as a practical matter stewardship of companies has to be done in an orderly way as directed by the owners, or it’s all going to be destroyed and a bunch of angry stakeholders will be angrily looking at the nameless faceless bureaucrats who f’d the whole thing up for everyone.
