UWC is parody and effective method of discrediting?

I like these people's objective and they make me laugh.

Will they have an impact?  If so, how?
Motivating those that already agree with them or changing peoples minds?
I think motivating is more likely.

The opportunity to parody European labor leaders is almost too easy given that their current slogans are "Anti-Austerity".

We want: More money for less work and you have to pay for it.  As usual, the unionized and government workers are better off then average working in the countries adding to the irony.

Have you ever notices how rarely the wages of protesting union workers are quoted in the mainstream press?
Here is one wage quote and more detail on Spain (even better).
