Well, he is from Texas. Not paying taxes is practically stealing from the state, and thieves should be shot!
Two things:
- Regarding your first point, you mean people would make sure they earn, say, 100$ less to get 1000$ extra in SS? It can't be that hard to make the system so that by earning 100$ less you can only get 50$ extra in SS.
- I probably am confused by your meaning of social security. Is it a government pension fund or what? That conflicts with the name, social security implies to me it is a sort of insurance against social problems (poverty, unemployment, etc). Quite different things.
= why the pension age needs to be adjusted. Jobs are also a lot less physically demanding than in the past (most jobs anyway), so you can work longer than in the past, too. Hell, even the labour unions here don't oppose to raising the pension age anymore.
