Neither one of these is getting fixed by simply increasing tax revenue alone.
When I goto the hospital and get an MRI and get billed through insurance and the cost is $2,000 and out of pocket I can pay $200 for the same procedure that looks like legalized fraud.
The same can be said for education. When the majority of student loans are given in such a way that a student can't default out of it, it reduces the risk on the lending party and so they give out a ton of cash and prefer the interest payments later on which raises the price of education.
Property taxes are also inherently low and should be raised and redistributed to lower income neighborhoods especially when so much property is already in the hands of the wealthy.
I would love to see higher property taxes because I have more faith in local governments than the larger bureaucracy.
