LOL! Now that is an argument that cannot be backed up.
First of all, Communism died a while back. What we have now are socialists who believe the corporations have no right to profits.
Secondly, entry level wages are not a union idea at all and they hate the premise. They believe that one man is as good as another and should be paid the same regardless.
This is why the H1-bs and other hard working folks are having so much success.
Management will reward them as soon as they prove themselves and not the other way around. Those who put in efforts will receive benefits in proportion to their contribution to the bottom line.
This is the way it generally should work. Communism has a totally different belief regarding this premise.
