Imagine the National Football League in an alternate reality. Each player’s salary is based on how long he’s been in the league. It’s about tenure, not talent. The same scale is used for every player, no matter whether he’s an All-Pro quarterback or the last man on the roster. For every year a player’s been in this NFL, he gets a bump in pay. The only difference between Tom Brady and the worst player in the league is a few years of step increases. And if a player makes it through his third season, he can never be cut from the roster until he chooses to retire, except in the most extreme cases of misconduct.

Let’s face the truth about this alternate reality: The on-field product would steadily decline. Why bother playing harder or better and risk getting hurt?…

If you haven’t figured it out yet, the NFL in this alternate reality is the real -life American public education system. Teachers’ salaries have no relation to whether teachers are actually good at their job—excellence isn’t rewarded, and neither is extra effort. Pay is almost solely determined by how many years they’ve been teaching. That’s it. After a teacher earns tenure, which is often essentially automatic, firing him or her becomes almost impossible, no matter how bad the performance might be. And if you criticize the system, you’re demonized for hating teachers and not believing in our nation’s children…

Perhaps no other sector of American society so demonstrates the failure of government spending and interference.
