spend the $15/mo and be done with it. All the other crap you have to
jump through is worth WAY MORE than $15/mo.

Yes. The price is stupid too high.

Or spend $20 and get a block of 8 (or 5).

Every time you stop a school, you will have to build a jail. What you
gain at one end you lose at the other. It's like feeding a dog on his
own tail. It won't fatten the dog.
