Mostly zoning laws, burdensome regulations and government subsidies, really. If housing, education and healthcare still cost in real terms what they did in 1950 then people could afford to work 20 hours a week if they wanted to, but they're stuck working 40 hours because of government policies that cause price inflation and cost disease.
> Climate change? Market forces.
Markets require consent to operate. The victims of climate change didn't consent and should have every right to sue.
> The persistence of the slave trade? Market forces.
It was actually market forces that destroyed the slave trade. The rise of factories gave the slaves something much better to run away to, which made "slaves running away" a thing that happened so much more often that the entire system started to disintegrate. It's not a coincidence that the Civil War was between the industrialized North and the slave-owning South.
Also, slavery is obviously the epitome of not being a free market.
> Prostitution and human trafficking, opioids, disintegration of the family, Facebook; all your good friend “market forces”.
Prostitution is dangerous primarily because it's illegal.
Human trafficking is slavery again.
The opioid crisis is caused primarily by the War on Drugs and failed government policies that make it hard and expensive to seek medical treatment while causing black market drugs to have high but inconsistent potency and all the other issues.
Disintegration of the family is mostly a result of social assistance programs replacing the need for social ties with government programs.
Facebook is lame but it's also in decline. That is how the market is supposed to work -- things people hate fall out of favor.
You haven't chosen very good examples.
