Does it though? Suppose that Wall St has discovered a strategy, like high frequency trading, that produces nothing but allows the one doing it to extract a margin that would otherwise have gone to the second-fastest trader. Many people are employed in a competition to be the fastest because being the fastest is rewarded but it's a zero-sum game where nothing useful is produced and the players each have to continuously spend resources to keep running faster in order to stay in the same place.
What benefit is the person now paying more for healthcare getting in exchange for this?

What if it's not all boats? Suppose it causes doctors to get paid more because people who have the wherewithal to become doctors could also work in finance, but it doesn't cause retail clerks to get paid more because Wall St isn't hiring them away from their existing jobs, and in the meantime they now have to pay more for healthcare.

Nobody with an existing job actually has to switch professions for Baumol to occur. As the pay gap widens, more kids would study finance and fewer kids would consider retail an adequate career, leading to a relative shortage of retail labor, raising retail wages.
