the consortiums on the NYSE are investing to be richer in the future. If you've already hit the $10M cap, what's the point? If your semi fab investment does well, you have to sell something else to stay within the law.

You don't just have to sell your assets, you have to spend the money from the sale too. If you still want to improve your future, that means you spend it on things that don't show up as wealth. Some of those are going to be great (education, prestige from endowments, charitable donations), but others are less so (bribery, lobbying, attaining political power, money laundering, self-interested "charities" like building a park next to your own house).
