>The first because a lower supply of labor is going to create breathing space for an entire working population who will see tremendous job upheaval due to AI automation. A lower aggregate demand on houses, services will also be welcome to take the fuel out of inflation, and maybe we'll regain some of that experience of true affluence, where scarce things (e.g. access to cabin in the woods, a rowhome in a walkable city, ...) are in abundance.
Many immigrants come to America to work and start businesses. That creates jobs. Even the day-laborers buy food, clothing, tools. If we cracked down on businesses that used illegally immigrated workers, that would be a much more targeted way to fight wage suppression.
How could inflation come from illegal immigration? Are the immigrants bringing in crazy amounts of money? Does the existence of more workers competing for an open position drive up the going wage?
If we want to reduce the price of housing, we need to build more houses. That's the key. The trouble is how to tackle the financial and regulatory hurdles that discourage building houses. Clamping down on immigration from poorer countries hurts the construction industry, which employs a lot of immigrants.
>Birthright citizen should be abolished because birth tourism and illegally crossing the border to have anchor babies are a vector for foreigners to participate politically and claim imho undeserved welfare benefits.
If we cared about people with foreign allegiances participating in our politics, we'd ban dual citizenship. If we cared enough about welfare costs to do unpopular things, we'd ban smoking and high-sugar foods. That would save a lot more in welfare costs, and our citizens would be healthier. On my list of priorities for reducing welfare costs, taking money from poor people who don't actually qualify ranks low. It's a mistake or crime that feeds people and gets money circulating in local economies. Not efficient, but not world-ending and probably not common. If you really want to find people receiving benefits despite not actually qualifying, look for senior citizens hiding their wealth as cash in their house.
>I think largely these are the stated reasons of the administration too.
Trump stated immigrants poison the blood of our nation. I'm going to accept that as his actual belief and reasoning.
