If it was just that, I would agree, but the problems went deeper than just "it's a start but not good enough"
The beneficiaries of the fund was a SINGLE union, not the whole state, and there were poison pill provisions ensuring that we couldn't do it again in future, so this would have been a one and done, not a prescident like we all hoped. So basically it was bound to fail to accomplish what we would hope even if it passed and would likely make things more difficult to get an actual tax, instead of just a narrowly applied windfall
