It is only the US that forces student loans that can't be dumped in any way.
There's a simple reason it can't be dumped except for things like getting crippled very badly. There's nothing to repossess. I mean in theory you could take the person's degree away from them but they'd still come out with whatever they learned and whatever network connections they made in college. On the other hand if you don't pay for your car loan the bank takes away the car and sells it to somebody else. The deal is if you could just get out of it like that no bank would make student loans. (Since people would and have declare bankruptcy to avoid paying for things like med school.)
Guess what. Technology workers like you and me aren't immune to the same damn laws of capitalism. Businesses will find a way to reduce costs and punch up their profits, no matter what populist measures are passed by the politicians.
I guess you missed it. The big bitch session about H1B's is that it isn't capitalism, it's cronyism. It's using government to interfere with the market by letting business use effectively indentured servants. They bring people in that don't have the knowledge about how much the job is actually worth, suppressing wages. Then when they find out they're getting screwed just like US citizens they have no recourse since if they raise a stink they lose their status and have to go back while the company gets yet another sucker. If this was capitalism then the foreign candidates would just work for somebody else that actually paid them what they're worth but with the H1B program they're prevented from taking any action. But hey, it's not as though this is the only time a company thought that using cronyism is a hell of a lot better deal than actual capitalism.
Any given program will expand to fill available memory.
