FDR used the commerce clause to mandate the first minimum wage. It passed muster with the Supreme Court in 1942.

300+ strikes in 1941.    
Nazis just started operation barborossa.  
FDR was also involved in secret navy war against the nazis in the atlantic.
the ruling was political.  
there 2 previous rulings by the supreme court that said the miminum wage was unconstitutional.  FDR had to have put a lot of pressure to get a favorable ruling.
the court ignored 2 provisions out of 4 provisions to reach that ruling.
