Incentivizing rich people and poor people

According to Republican theorists, rich people and poor people have completely different reactions to incentives.  

If you want rich people to work harder, you give them money.  It might take the form of tax cuts, or grants, or military contracts.  When you do give them money, they work really hard.

On the other hand, if you want poor people to work harder, you take money away.  You take away SNAP benefits, or Medicaid, or veterans’ benefits, or raise their taxes.  When they are hungry or homeless, they work really hard.

It is quite interesting.
