Eligibility for prek

My child recently turned 4 and I started searching for prekindergarten because - obviously. This is what I stumbled upon. I've called many isds in our area and these are the requirements.
Basically you have to be educationally disadvantaged, broke, or in the military. They charge tuition now and I just can't grasp it!! Anyone else have this problem?
Would you pay tuition for your child to attend pre-k?
