I don't care that they come over, immigrants as long as they're healthy are generally a net gain.
the issue is because of min wage laws, their is no legal wage at which they can be employed once they come over, and because of ridiculous building restrictions its impossible to build housing in which they could afford.
min wage laws and building codes(other then general safety) are a detriment to immigrants and the poor as it prices their labor and housing they could afford on such wages from being built.
