Does anyone else think it's time to tax the churches?

[Vox Moi]

59. Churches, universities and hospitals are all tax free and maybe ...

They should pay property tax.
Sound draconian? I agree.
I'm not sure what can be done but it's clear that something is needed.
Hospitals and colleges are notorious real estate buyers and every square inch is off a city's tax list.
Harvard University has an endowment of tens of billions and is a rabid real estate buyer ... all of it tax free, and they still charge enormous tuitions.
Most cities have a large hospital that seem to always be expanding and buying property.
I do not doubt that health care and education are important but the political and financial power of large hospitals and universities leads to wanton acquisition of property and political power and to waste and extravagance.
To call these institutions non-profit is a real stretch.
If they are tax-free then they should be required to give something tangible back to the community like affordable health care and affordable tuition.

Contributions to non-profits should be taxed at some nominal rate that would still provide an incentive to donate.
Suppose it was 10%. What's the problem
