There is no situation in which government should fund efforts to nudge our behavior. They can require paying taxes. They can forbid murder and rape (except by those with special connections, like Hillary and her horndog hubby). But they cannot ethically compel or even nudge our actions beyond passing and enforcing criminal laws.
One thing I would like to see under Trump is the elimination of ALL tax laws designed to encourage/discourage behaviors or other social engineering. Taxes should exclusively serve the purpose of collecting revenue. The same goes for other social engineering efforts. Let’s cut government back to its proper role and nothing more.
That’s part of what made the tax code as complicated as it is - trying to use the promise of tax breaks and rebates to shape behavior.
