@hightor,
Those are the usual responses to reduced government involvement in the economic activities of its citizens. However the facts reveal a different set of outcomes.
We have markedly reduced our carbon emissions through the replacement of coal with now abundant natural gas - a direct result of the fracking & directional drilling revolutions enabled by regulatory reform - and have achieved far more emissions reduction in the last few years than were achieved in a the previous decade of subsidized wind and solar power.
I'm not aware of any data indicating a rise in workplace injuries, though I will gladly review any you can point out.
Our infrastructure has suffered from an overall, lack of investment(and a good deal of misdirection of investments that were made) for several decades. Our current administration has done nothing to accelerate the long term decay of existing roads & bridges, and both parties appear to agree on the needed overdue increase in those investments. The only difference I see is the proclivity of Democrats for poor use of invested funds, as for example in truly loonie projects such as the long defunct and now cancelled California high speed rail line from LA to San Francisco ( nice idea but no one ever addressed the cost of the needed tunnel under the San Gabriel mountains, or the cost of a grade separated line from Livermore to SF.)
Economic & political histories are simply a series of "momentary" gains & losses: in the long run we're all dead. The beneficial effects of the recent economic situation are undeniable, and, as history amply confirms, the long term results of socialism and government-controlled economies are poverty and tyranny.
