Always the plumber who can afford every other toll but not the very low priced congestion pricing. No other occupation ever gets mentioned so we must think of the non-existent hundreds of thousands of plumbers who can’t afford it.
I'd say everyone who's working in the various home improvements/renovations, so carpenters, tillers, HVAC/boilers installers and maintainers, roofers, painters, kitchen designers, those who install plancher or carpets...
The MTA did a 10 year long study. It wasn’t something that appeared out of the blue.
