Is this why private universities look more appealing than public universities?

Some of the nonprofits has gotten so big in recent years. Tax revenue loss from just one organization can be sizable. It is less consequential for smaller nonprofit organizations. One could limit the size to be tax exempt. Tax exempt up to a certain amount, anything beyond is taxed at a lower rate. We have to ask where we are going with it if they are allowed to grow tax free. Does it further contribute to the inequality we see now? It seems that way with the higher ed. While we cut funding to public universities, tax break to wealthier institutions gets bigger.
