I think if you want a high-quality train service, you should pay for it through higher fares. Saying you would pay higher taxes is sly language for saying you want to others to subsidize you.

In Vietnam, even in smaller cities, there are at least three different ISPs with citywide GPON FTTH. The fact that they weren’t forced to share a government lowest-common-denominator physical layer means that we are now seeing some competition around improvements to that physical layer, with one ISP offering much faster speeds made possible by incrementally improving their physical network. The others will be encouraged by competitive pressure to do the same, or maybe even do better.
And per the IMF there are huge subsidies to fossil fuels in the US:

I think if you want to pollute the air and cause climate change, you should pay for it without those of us who use public transit subsidizing it.
