Ed, you have proved that you are a really good deciever. You state something that is almost true - that germany has no minimum wage (though construction workers do) and then indicate that this lack of minimum wage is a reason for their success. But then there is the rest of the story, which ed does not want anyone to know.
First, nearly all wages are set by collective bargaining in Germany. and those wage rates are enforsed by federal law.
And second, that it now looks as if Germany will very shortly have a minimum wage.
Here is the link to the information (if your a con, you probably do not want to read this info)
