Average people might be tire of paying high salaries

Frustrated with Democrats, some large unions cut back on donations - The Washington Post

Most people are likely figuring out that they are never going to be fortunate enough to get a union job and thus see no reason to pay for their high salaries, health insurance, and retirement programs. The median voter is not a union worker but rather someone with an income and job security far below a union worker with no hope of getting a union job. Thus the unions workers are no longer the little guys but rather the fat cats, who are not even perceived as particularly deserving. Most Americans still think those that make it big based on hard work deserve their riches. But a average Joe making twice what average Bob is making just because he's at GM rather than Toyota. Americans aren't down with that.
