Any and all minimum wages should have been declared unconstitutional by the Supreme Court as they were initiated. Along with businesses reserving the right to refuse service to ANYONE for ANY REASON.
Actually, regulation of minimum wages and other employment conditions is well within the traditional police powers of our state governments. They are completely free to establish good laws, bad laws, or no laws at all in these areas, as their elected representatives see fit.
On the other hand, Congress has no jurisdiction whatsoever in these areas, except as that presposterously read into the Constitution by the SCOTUS's rediculously expansive view of the commerce clause. If the Fed's stuck to their remit under our Constitution, Congress could meet about a month every other year to handle truly important federal questions, while most of what your congresscritters in the D. Of C. spend their time wrangling about would be dealt with in your state capital, just up the road from you.
