Oh no, not the evil "profit"!
The mater of "using" is what I find interesting. It has a socialist tinge to it. The evil capitalist pigs are merely "using" the poor working man ... I look at at it as more of a mater of trade. Some trade their labor and others trade their cash. Both benefit from the transaction. We just need to be clear on what we are asking the government to regulate, for there are alway unintended results. If we want the government to require we check the immigration status of everyone we trade with, fine. Just be aware it can lead to retailers also checking the immigration status of everyone they trade with also. I do not think this is a path we want to head down, but I'm just funny that way.
I say the border should be fortified so that the best way in is legally.
Castro is a nice guy, anyone in his jails will tell you so. Funny how Castro and his socialist friends would also talk about workers being used or exploited to make a profit. A Canadian company runs a mine there and pays the workers thru Castro's bank account. Best not to support Castro, or socialist thinking over here.
