Even the cartels have said the drugs come through tunnels. But let's go with the whole, wall stopping the drugs and gangs. Let's see what happens when white people don't have access to drugs, and more of them start making, and dealing drugs. Is anyone forcing them to do drugs?
Let's say there are fewer drugs, and less crime. That calls for less DEA, and less law enforcement, which causes those people to be out of a job.
Cities make revenue from tickets, and people bailing themselves out of jail. How are they going to replace that money?
Let's say fewer drugs causes more black and latino people turn their lives around (which is good). Are white people going to sit back and accept black people doing well in life?
Will privatized prisons just cease to exist?
Everything bad is there on purpose because someone benefits from it.
Why aren't people who HIRE illegals being penalized? Is it because most of them are white, and anything that puts a large amount of white people in trouble is handled differently.
