Some of the public funds come by way of Pell Grants. What's so terrible about poor kids getting a top-tier education?
Other mechanisms are research grants. You don't think it's in the public's interest to incentivize graduate students at top institutions to do socially beneficial research?
Help me understand what your objection is to federal policy, and what you wish federal policy were instead.
You indicated a problem with the way federal funds are spent. What section of what federal statute should be changed? In what way should it be changed?
I spelled out pretty clearly why somebody might have issues with taxpayers subsidizing the tuition of a Harvard graduate.
You expressed disapproval of the fact "[t]hat public funds can go to private schools like Harvard."
I tried to guess what you might mean, but it appears you've found those guesses insulting. So why don't you just clear it up so we aren't left guessing? What are the specific changes to federal law you propose as an alternative?
In this case though, Harvard doesn't need it, and there are definitely enough Harvard graduates in the upper echelons of both the public servant and elected politician career paths of the federal government apparatus for no harm to ever happen to Harvard. But it's still an important point to keep in mind I think.
