An article by Kim Geiger in the Chicago Tribune casts a little light on how the members of the Chicago Teachers Union are thinking:
Under Lightfoot’s proposal, a teacher with a bachelor’s degree and 10 years of experience today would see his or her salary increase to $95,604 by year five of the contract. That amount is $11,000, or 13%, more than the current teacher with 15 years of experience and a bachelor’s degree earns today. A teacher with a bachelor’s degree and five years of experience today would go from a salary of $58,315 to a salary of $81,701 in five years. That’s about $6,500 more than the $75,083 earned today by a similar teacher, or an increase of about 2% each year.
There are all sorts of problems with that calculus but I’ll just consider a few of them.
First, they want to be paid based on inputs rather than on outputs. I honestly don’t know any private company in which that would be the case. They’re estimating that the value of the hypothetical teacher five years from now will greater than the value of that same teacher today so his or her pay should reflect that. That’s not the way things work in the real world. You’re paid based on the expected outputs of other people who may only resemble you superficially.
I know more and am, presumably, more valuable than I was 30 years ago. If I want to earn more than I’m making now in practical terms I should look for another job. The problem that the Chicago teachers have is that they’re already making more than not just anybody in nearby districts but more than teachers in the other major school districts in the country.
Second, since every dollar received by a Chicago teacher must come from a real life resident of Chicago, as a matter of practical necessity teacher pay must be tethered to the ability of the people of Chicago to pay. Calculate the total earnings of all of the people who live in the city of Chicago. For teacher pay to rise faster than that amount you must take more money away from those other people. Eventually, people get fed up and move away. That’s has been happening for years. As fewer Chicagoans are available to pay taxes, even more money must be taken from them. It’s a vicious circle.
