I would personally rephrase the previous comment as one of choice: for a free market to function you must have a reasonable choice to say "yes" or "no"; if you're strongly incentivised (or even forced) towards saying "yes", then that's not a very free market.

And that what's skewed here: as a (low-income) labourer, I often don't have all that much choice but to say "yes" since my bargaining power and alternatives are extremely limited. Often times people can't really "compare options".
