US citizen here, in the highest of all possible US+California tax brackets, who is very enthusiastic about rail and non-bus public transportation.
It's not that I don't want to pay taxes for rail - I do - it's that we already ramped the tax collection all the way up to 11 without doing any rail.
Once you're at >50% effective tax rate[1], where do you go from there ? I can't possibly favor any tax increase - it doesn't matter what for - since we are already past (what I would consider) "peak" taxes.
[1] 53% - although in my case, closer to 48% due to minor things like 401k and HSA, etc. Yes, I am one of the suckers who is in the highest bracket but pursues no exotic tax avoidance.
