Transit Strike in New York City

Collectivist transportation is not very modern or effecient.Now we have the overpaid New York city transit workers blackmailing the public because they have a monopoly.Check out the wages these people get:

The union said the latest MTA offer included annual raises of 3 percent, 4 percent and 3.5 percent; the previous proposal included 3 percent raises each year. MTA workers earn around $47,000 to $55,000 annually.

Not bad for people who don't need a college degree.If these workers feel they are so underpaid why don't they quit and go into some other industry???
