The new deal was a huge failure. only the outbreak of WW2 ended the great depression, to which socialist policies were only prolonging the pain of the great depression. Bad working conditions is not == capitalism. Soviet working conditions were not the workers paradise. Working conditions in China is still not the workers paradise. Working conditions in North Korea are not the workers paradise. Need me to go on? I can do this all day.
and by the way, the oil for reading at night was only one of many many great benefits. Ford bought cars to the working class for example.
The Laissez-faire capitalism of the gilded age came crashing down in a spectacular depressions, the benefits, which only some could afford, were short lived when suddenly there weren’t any jobs. The New Deal gave people back their jobs so we could again afford the luxuries of past inventions.
You see. I too can spin a narrative where socialism brings all the good stuff and capitalism none.
