As for your so-called "open borders", they're still open. People are arriving and leaving the USA every single day. The only thing Trump has done is to prevent refugees from coming across the USA/Mexico border.

Under Joe Biden, your crime went down - WAY down. If immigration was so dangerously bad, that would not have happened. GDP growth was the highest in the G7, because immigrants buy things, and use services. Investment in manufacturing was WAY up and inflation was tamed. Biden even managed to outsmart Trump and OPEC, to get your gas prices down.
