Most of these folks are NOT Mexicans. I know, I lived in Mexico right on the border for several years. The majority of the folks in this group are actually central americans who are pure economic migrants which aren't legally allowed to receive asylum from us. They are encouraged by ads in their local media which are placed by smugglers and NGOs, and brought to the border as a for profit activity. Mexican cartels control the border and make a huge amount of money smuggling people in. The ones too poor to pay the cartels get coaching from NGOs and charities on exactly what to say to successfully get asylum on political or other covered persecution grounds. These NGOs/Charities get their money on the back end from US taxpayers who pay through the nose for these orgs to house/feed and assist the aliens. Trump had dismantled the asylum racket, as he did not depend upon the swamp for campaign contributions, Biden and the dems are dependent on their funding, so just like Planned Parenthood, Teacher's Unions, foreign aid, and other budget items, the dems get campaign contribution kickbacks from the groups that receive our tax dollars. Not a lot of hope fixing this unless we manage to get 61 votes in the senate and a majority in the house in 22, at which time we can defund this garbage.
