While OSHA, workers comp, EPA, etc. minimum wage, etc. laws and regulations may have some sense, we have to realize that these same laws also reduce employment and push industries overseas and make many of our overseas competitors more competitive.
This is predicated on the false premise that it is necessary to have an open market with countries that have lax labor practices. If you levy a 2000% tariff on countries that exploit slave labor American labor can become competitive again. The same can be said about countries that do not have any emission controls.
