Those are the types of measures that have been attempted for generations. It’s how we got here. There is no hope changing a system from within that is designed to serve the interest of the wealthy. That system will only ever offer temporary measures when it feels it is within its own interests to maintain itself. Social security and Medicare were not some idea FDR came up with to help the working class. They were fought for a pressured for by socialist, communist, and trade unionists literally taking up arms and threatening capitalist production. These social programs were an offering prevent the actions that threaten to tear it down. They were an offering to the working class to prevent revolutionary change.
But, here we are again. Hoping for another FDR without any of the material threats to capital. That will not come about without organized labor and with a means to defend themselves.
