Oh, you were serious! Well, I think what they need is Democracy first, then unions. Communism theoretically eliminates the need for unions, but the reality is that it's just a dictatorship. Unions in China would likely either be co-opted by the Communist party through subterfuge, or through "reeducating" the misguided leadership and defining the unions - thus landing them right where they are, with a new bureaucracy.

Unions represent the spirit of the checks and balances envisioned in the U.S. Constitution. It is only by being of near equal power to the company that employees can negotiate for fair compensation and treatment. Without that, they're just resources. It's an effort to use human nature to gain good outcomes.
