The L train to Bedford Ave carries way more people now than it ever did in the 1940s, when Williamsburg was a modestly dense working-class neighborhood. On the other hand, those letter lines to outer Brooklyn are much less used today than they were in the 1940s, as are parts of the system in the Bronx. And, of course, there were elevated lines over Second and Third Avenues in the 1940s.
The parts of the system that run at crush capacity are already running with the highest possible train frequency. Some of the lines might not seem maxed out on headways, but they have to deal with interlining; the frequency of the F train can't be increased because the line it shares with the E train in Queens is fully loaded, etc.
If the MTA were simply a city agency for which the mayor was directly responsible, it would be possible to channel voter anger (and there's plenty of voter anger, by the way) into action. But it's the governor who really has the most control, and he's responsible to a wide swath of voters outside the New York City region (who tend to want less spent on the MTA in any case). Plus many voters don't really understand how the MTA is structured, and elected officials can hide behind this independent-agency arrangement.
