Liberal babbling.I did some research into exactly how much tuition costs at places like Regina and then compared them to the public costs. The Regina information was found from a PDF on tuition rates from the Diocese of Davenport for 20-21 school year, the other from US Public Education Spending.
Regina K-6th - $9,630 a year.
Regina 7-8th - $11,915 a year.
Regina 9-12th - $17,995 a year.
Iowa Public K-12th - $11,656 is spent a year. 3.96% of our state taxes go towards public education so a 4% flat tax would absolutely cripple public education. One thing to note is that nothing was listed for how many students were special education needs students, I suspect if that was removed it would be even cheaper.
Btw, stop bringing CRT into the discussion. CRT being taught in elementary/middle/high school is a red herring made up to scare gullible fools. CRT is only being taught in a high-level college course and would be something a regular Bachelor's degree wouldn't even sniff at. It would only be seen at the Masters or Ph.D. level.
