Not trying to drag this into an argument for the Cesspool (where I refuse to wade), but our per capita income is always skewed by Fairfield County and some parts of western Hartford County. For example, something like 1.5% of the State's income taxpayers lives in Greenwich, but they pay over 13% of the State's income tax revenue. Looking at the State's per capita income as a metric and saying, "see? We should be spending more than we are," doesn't necessarily imply that you or I (assuming you're not one of those 1.5%) can afford to pay more in taxes to accommodate new State spending on higher education: it just means that some people in this State have really, really high incomes.
(A similar argument is, "Connecticut residents are only getting 70 cents back for every $1 they pay the federal government in taxes, so I must be getting shafted." That doesn't necessarily mean that you or I aren't getting our money's worth, it just means that the top end is paying a big, big amount to the IRS. The State's net return for the middle 98% of the population, taking away the richest and poorest 1%s, is probably on par with most of the rest of the country.)
Also, I think it's really a tenuous argument to tie State spending on higher education with money earned by people who generally don't take advantage of it. B isn't really a function of A.
Don't get me wrong - I am utterly thrilled by this plan because for once the State would be spending billions on things I like. It is, however, a legitimately significant expenditure that will make UConn stand out, not something that we should have been expected to do all along just because we have some rich people in the State.
(In my opinion.)
