Public employee unions and elimination of the Middle Class

Michael Barone reports:

many on the political left complain about the disappearance of the middle class, the alleged tendency of our economy to produce hefty income growth for those at the upper end of the economic scale and relatively little income growth for the large number at the lower end. Interestingly, this tendency toward income inequality is most pronounced in states that have been voting Democratic in presidential elections—especially New York, New Jersey, Connecticut, and California. Income inequality tends to be much less in many states that vote heavily Republican. New York, New Jersey, Connecticut, and California have imported many high-income earners and low-income immigrants and have been exporting many more middle-income earners. This process is accelerated when, as in these four states, high-income earners have been eager to vote for Democrats backed by public-employee unions: The same people who have been complaining about this trend have been causing it.

Not everyone can be in a union,if everyone was it would nullify the advantage of being in a union.The middle class life-style seems in short supply in these union states.
