I was referring more to the socialist aspects - taxing corporations and wealthy individuals, the social security program, unemployment and welfare, workers rights, financial regulations, etc.
My opinion is that FDR didn’t really love any of those things, but saw a potential for widespread social unrest, and tried to mitigate that by working out a deal with the oligarchy.
This lead to the terms “liberal” and “conservative” defining the 2 parties and seems to have laid the groundwork of the extreme bifurcation we experience today.
