The issue seems to be people don't like the idea of only keeping 50% (or less) of their income + making 50% less to begin with. Most people that work at big tech get their big salaries because the companies profit in data-mining ways that would be more regulated in Europe.
To get the US towards building much more transit (and other infrastructure) there are many hurdles, but one of the main ones is building useful things for non-obscene amounts of money.
The thing is though, it's not even most higher-salaried tech workers that we need to tax heavier. We need to tax the rich. When I say the rich I don't mean people making 300k/yr. I mean people making a million or more per year. We need to massively increase the marginal tax rate at around $3 million to around 90%. This was how it was as recently as the 80's, and repealing those taxes has led to an increase in wealth inequality this country has never seen.
