The MAJORITY of those coming across that border are coming for work. If some are coming for welfare, then we need to do something about welfare. Sure, "that shits going to be around for years to come," but what is the point? Is it really okay to give stuff to lazy Americans? Then lets do something about that...not continue to blame "illegals" for somehow "bankrupting the country."

If legit people could come across the border more freely (as they did in my grandfather's day), then those who are not legit would be easier to catch.

It's just like any other prohibition. If the cops are trying to bust drug dealers, it takes them away from busting murderers and rapists. Catching and convicting drug dealers is easier than the latter...which is why the majority of people in prison are there for non-violent drug offenses.
