Yes, let's have money decide who gets or doesn't get food or shelter or medical care... oh wait.

Snarkiness aside, rich people can already buy citizenship in most countries, even the U.S. It's by far the fairest and most objective system to decide who gets in or doesn't get in. It also has the positive side effect of selecting those least likely to mooch off the state (a popular fear amongst those against immigration).
