That is correct, they can't. This is how wages naturally go up. The answer isn't bringing in illegals to do the job, the answer is to focus on our drug problem. The Democrat states are legalizing drugs instead of fighting against them. Even if dope is legal, that still doesn't mean that employers will stop drug testing.
The War on Drugs did not work
Decriminalization does....it works around the world
So how is it the war on drugs has not worked, but you leftist think the war on guns will?
When you make something legal, more people are going to try it; more people are going to use it. In spite of the myth pot is not addicting, I've seen too many situations that convinced me otherwise, such as the jobs I talked about.
In any case, if people can't get jobs because they are addicted to pot, and we are going to promote it's use by removing prohibition, then you're going to claim we need more invaders to do the jobs Americans can't do because they are too doped up.
What you just wrote is the perfect example of how liberals solve problems, and that is to create more problems in it's place. It's why the left should have no leadership in our federal government. They can destroy their states, but they should not be allowed to destroy the country.
