This article has a strong slant. If we can look past that, we should consider the claim: everyone having skin in the game is more democratic and leads to a better aligned government.

But everyone won’t have skin in the game. We’ve played this game before. The uber wealthy and politically connected kids will either get outright deferments, or cushy positions that never have them sniffing any danger beyond carpal tunnel.
It’s no different than the republicans that are violently against abortion and then you find out they’ve funded multiple for their mistresses. They’re perfectly fine with a law banning it because they know it will never apply to them.
