Who Are These 'Taxpayers' You Speak Of?

Tyler Cowen points out this interesting proposal from a group of students at UC Riverside:
Instead of paying tuition - currently at $12,192, not including mandatory fees, room, board or books - the "UC Student Investment Proposal" would require that students commit to paying 5 percent of their annual income for 20 years after graduating.
At the very end of the article, we get this fun pair of paragraphs:
"I'm against it," said Jessica Greenstreet, a politics and theater major at UC Santa Cruz who was not at the meeting. "Public education is a public good, and should be paid for by the public, through taxes." 
In fact, Greenstreet's tuition is paid for through the GI Bill because her father was a Marine.
ZING! But not really, since the GI Bill isn't funded directly by GI's but by taxes paid by taxpayers (only some of whom are GI's, and one of whom, presumably, was her father).

Greenstreet doesn't seem to realize that, were this plan to go into effect, she could be among the benevolent hoards of taxpayers blessed with the opportunity to provide more "public goods" through tax dollars. She would be directly funding her own education, using skills that her education helped provide. So, you'd think this plan is a win-win for her. But I'm guessing that when Greenstreet said "taxpayers," she really meant "other taxpayers."

By the way, does Greenstreet major in "politics and theater," or are they two separate majors? And what's the difference between the politics major and the theater major at UCSC?

Graduates of one program are prepared for a life spent pretending to be someone they're not, neurotically attempting to please everyone they meet, and ultimately blowing tons of other people's money on lavish productions that may or may not provide any long-term social good; graduates of the other program become actors.
