I was talking about the greed of the unions, not the "greed" inherent in capitalistic companies. Even the accidents that Texas and the Gulf Coast has had recently pale in comparison to what was going on in the 1940's and 50's, and even the 60's. Dow Chemical's Texas plant (the largest in the U.S., built mainly in the 1940's - 1960's) had over 250 deaths in a single year in its early years of construction. There were no explosions, just construction. You would probably have to go back more than a decade and include every chemical plant and refinery in Texas and Louisiana to get anywhere near 250 fatalities. The Cuyahoga River in Ohio was so polluted with chemicals in the 1960's that it routinely caught fire. The U.S. doesn't have anything like that now. Most of the most serious Superfund sites and major toxic waste disasters in the U.S. (Love Canal, etc.) were created in the 1950's and 1960's. The Clean Air Act and RCRA in the 1970's were the main driving forces to clean up the chemical industry. The EPA and Congress have not done anything nearly as productive as those two pieces of legislation since then.
