Asinine idea of the day, there are some many wrong aspects it's even difficult where to start. First, $100k is a big but not absurd amount of money for an American or European (it's roughly 1 year salary of a good engineer), but everywhere else in the world it's much harder to save that kind of money - it's closer, say, to the price of a decent house for a middle-class family. The efffort to save that money will be very different per country of origin, which is very unfair. A Brazilian engineer has 3X better wages than an equivalent Chinese engineer, due to different currency valuation and salary standards. People will start paying for this not with cash but with bank loans. These will be relatively high-risk loans so in practice, people will pay $100k to the US treasury, and maybe another $50-100k in interest to some private bank. And even if the loan is from an US bank, this doesn't necessarily mean "even more money injected in the American economy" - these days, money that goes to banks rarely benefits society in any significant way. Having $100k in cash doesn't necessarily prove that you have the kind of skills that would ensure a well-paid job, and benefit the US economy. Maybe you are a mediocre professional, but you just inherited this money. Or your family helped realize their loved son's immigration dream, so you can only pay for the green card because dad sold his house. Or you just worked your ass off for 20 years in low-pay jobs, having a lot of discipline to save money. Or you made a loan (item above), maybe using family's property as collateral so you don't even have the merit for that loan. End result, a low-skilled worker being granted a green card and maybe becoming a liability to Social Security after failing to get an US job.
