At best; I think no one should be able to have more than about 500 Million. You get one house, and one car for each adult family member if you're married with non-adult kids. Adult kids don't add uncounted vehicles; they have their own limit. Anything that is seaworthy or airworthy counts as about as much "Wealth" as you initially spent on it minus a reasonable depreciation rate yearly as determined by the market, so no buying a thing and having it lose 30% of it's value the moment you drive it off the lot after buying it.

Additionally; to block too many shenanigans; wealth added by any property that is bought sticks; 3 years at minimum. This prevents people from storing too much excess in property and shell-gaming it. A company you own or have stake in cannot lend (in a long term) or gift you property in excess of 1% to 10% the wealth limit. (Depending on what the thing is). Companies may also not hold property or money in lieu of an individual personally; everything the company owns must have a global company function; and not personally benefit one or more people only. (Basically no executive-only or owner-only Jets; everyone from the tiniest manager on up should have access to it if there's a business reason for it)

Oh I agree that even 2 billion is too much, but my reasoning is that proponents of capitalism often make the claim that capitalism drives innovation (you try to fill some market niche in order to get rich) so if they are right, then 2 billion should be enough that this still works.

I had yachts depreciating to zero in my example because it's estimated that you have to spend about 10% of its' purchase price annually anyway, so anyone keeping a 20 year old yacht around is going to be spending a lot of money on it that will fuel other parts of the economy.
