“Self interest is a piss poor excuse for not enforcing the law.”
The way the system works, they don’t care because they get their money by making the employer pay. If they actually had to collect, it would make a difference.
“States have a huge role in regulating the renting leasing and residence of all property”
Then private property does not exist in America. If I can not rent my place to whomever I want, then my property isn’t really privately owned, is it? States have no right to bar private commerce.
The State has the power, under the Constitution, to regulate such things as it and the citizens who elect it see fit.
If the residents of a State want to pass a law that you cannot rent to someone without them providing proof of legal residence that is not an abrogation of private property nor against the Constitution.
States ban and regulate private commerce all the time. Try selling raw milk. Try opening a business without a license. Try to put up a sign on your business saying “no ________ allowed”.
Try reading the 10th Amendment again and then come back and tell me that the States have no such power under the Constitution.
