@wjmaggos really it's one of those cases where the reason we aren't implementing a solution is because society is legitimately split on what to do. We simply don't have a consensus about how to handle immigration. Without consensus we are simply paralyzed.
It doesn't take any conspiracy theory among employers or anything like that, the public simply doesn't have a consensus direction to go, so we're stuck.
Maybe someday we will have public sentiment solidify in One direction or the other, but that's not going to happen anytime soon.
