Some of those game-playing, grown men can throw fast balls over 93 mph, knee buckling breaking balls or both. The rest of those men can hit those fast and crazy pitches better than 49,999 out of 50,000 people. That is a much smaller percentage than the high percentage of people capable of teaching High School Social Studies. Because of the extraordinary elite ability, millions of people will pay to see those grown men playing that game. That is why, thise players expect to be paid elite level salaries.
