Not if the earner centralizes their profits and hangs on to the capital - then it just furthers our wealth inequality and harms poorer Americans at the expense of wealthy visa-holders. They can still drain our system, they just do it the Walmart way. Letting people in for a brick of hard cash seems much less likely to foster the sort of values that would result in visa holders not wanting to loot the country for a quick profit.
