" But the so-called leaders, the parasites who prey on both their members and the taxpaying public..."
There-in lays the problem. The union bosses, primarily the bosses of the huge national unions. The smaller, local, public employee unions just want a fair shake.
This is a big issue, and cannot be intelligently discussed unless broken down into specifics. Anyone with an ounce of sense recognizes that there is a symbiotic relationship between employers and employees. Robber baron style corporations and unrealistic union rules/demands poison the well. But unfortunately, without a union, the corporations will not play fair. Empirical this is a truism.
