The New Deal was just a head fake while they dealt with the real enemy - communism. I do have to give the owners credit (or more accurately their advisers) for how they played the long game - a work of genius that has totally won.
Pyhrric victory. In so winning, the capital class makes overthrow and revolution impossible to avoid. The threshold point goes ever higher, and by the time you're putting the screws to the borgeouisie and formerly comfortable middle class people it's too late: you're trying to exclude those who have enough power and leisure time to effectively mobilize against you.
'Totally won' means there's nowhere to go but down.
Technology can be used so that no matter the number of poor people that want to revolutionize, they will be defeated. You can pick out and get rid of the leaders before they even get a chance to get going, and even if they do, you have control of a very capable military and police force.
Resource depletion and pollution might be their formidable enemies.
