Which is the number set by the medallion system. My original point in this line of argument was that one of the main reasons cabs don't contribute to congestion in the city is because the number of cabs allowed in is capped. You're the one who wants to make that number bigger.

Also, I didn't realize that the 37'th percentile of income (36'th percentile in NY [1]) did not count as lower middle class

The labels are flexible depending on who's drawing the boundaries, I'm sure. The point is that I wasn't contradicting myself when I said your plan would both cut a certain class of jobs and increase traffic, I was simply saying that you're replacing fewer higher-paying jobs with more lower-paying ones. Where we disagree is that I think in this case that's equivalent to giving rich people a break and forcing more of the city's service workers to live further away, and I assume you don't.

If the congestion tax costs less than $24,000/year/cab, consumers still pay less for a taxi.

You're taking the savings from the medallion and labor costs that you posited above and assuming they'd be passed directly to the consumer, but that's overly simplistic. More competition means marketing costs go up, which drives the fares back up a bit. The congestion tax is presumably convincing fewer people to drive to work, which increases the demand for cabs, which drives the fares back up a bit more.

The point was not "you are wrong about consumer prices going down", it was "you have to start modeling the problem more carefully to have a meaningful conversation about it". You're probably right, consumers would save money, but again, given who the consumers are (oversimplifying: rich people), I don't necessarily see that as a good thing when it comes at the cost of cabbie pay.
