Since Sports Athlete's and Actors have Labor Unions why do the Democrats support Labor Unions and support a Progressive Tax System why do they suport higher taxes on their Union Brothers and Sisters many which make millions of dollars a year. Am I right that the reason why Sports Athlete's make so much money is because of Strikes ? Also my point is not all Rich people are CEOS of Big Wealthy Corporations ?

Because the people in the sports unions make up under half a percent of the total union membership in the U.S.; they are for the majority of the people.
