This is all problem reaction solution. In anarchy / free market the land would be privately owned effectively creating borders.
With no welfare state the immigrant would need wealth or some sort of sponsor (a charity, family, employer, or other contact willing to allocate their own resources to support them.)
Of course we don't live in such a world and so nations have borders. The UN, DHS, and a bunch of NGOs literally paved a road and paid people to immigrate to the US. This is an intentional demographic attack. These immigrants are pawns just like US citizens.
Biden opened the border claiming that legislation was the only way to fix the border, but he was simply not enforcing existing law. Drumph proved this to be true by simply closing the border. But he is also using the problem to normalize militarized streets and people being snatched up.
ITS ALMOST LIKE TRUMP AND BIDEN ARE PART OF THE SAME NETWORK AND EXECUTING THE SAME PLAN.
No voter is responsible for what "elected" leaders do. This is all pro-wrestling.
