Re: @jpo234 - I wish...
The problem with capitalist efficiency is it currently manages to externalise most environmental costs.
If the cost of pollution were somehow priced into all purchases of raw materials and energy, then a "full-blown capitalist" would immediately work to minimise it.
This is actually how health and safety happened in the USA. Employers were required to pay fixed levels of compensation whenever an employee was harmed - regardless of fault - and suddenly they magically started providing safety kit (guards etc), requiring it to be used properly and training their workers.
That system replaced the previous "sue them if you're able", which didn't work as fault had to be proven. The lawyers didn't like this of course, so "sue 'em" came back.
