"An elementary school custodian could afford a mortgage, a car, support a family of 4 and go on vacation on just that single income. " Can I ask what you are basing this off of? I'm fairly skeptical of this claim.
The head custodian at my elementary school (in the 80s) was a friendly guy that loved talking with the kids. He'd talk about his life, ask us if we did anything fun over the summer, and tell us where he went with his wife and kids. The school was in a small town in the rural midwest, not particularly affluent, but not poor either.
The elementary school where my kids went (in a much more wealthy district) doesn't even have a custodian that I'm aware of, just a 3rd-party cleaning service that hires immigrants for as cheap as possible, and I'm sure doesn't offer healthcare or even full-time work. They have too many highly-paid administrators to afford a custodian.
Ok so you're moving the goalposts here. What you said was a custodian (who I'm assuming did a lot more than just clean) and now you've switched to a head custodian and are comparing him to contract workers. So you're comparing two different jobs in two different school districts. Now is it possible that they've eliminated or reduced those positions? Sure, but you haven't actually shown that at all. Like I could easily counter with the fact that the school my wife teaches at still has a head custodian but I don't know what his family situation is and we'd just be trading anecdotes. So do you have any actual evidence for your initial claim? Because the overall stats with wages and prices are the opposite from what you claim.
