This is such a bad take. Indians are stuck in archaic immigration laws, pay taxes for US services they can never use, send whatever small amount they can save to family in India. And you have a problem with that.
The rich love immigration. They make way more money off the backs of workers.
First off it require a bunch of them to leave cities and there is a remarkable tendency for people not to do that.
Second, the work is extremely grueling. Many Americans are no longer able to do that sort of physical labor.
Finally, the spiraling cost of food would be so inflationary that we could not afford to pay the people doing the back breaking labor enough for them to consider it worthwhile compared to their other money making options.
Its a quintessential slippery slope.
