Socialized industries, like the ones stated above, are collectively paid for by all citizens and provided to all citizens equally. You don’t pay every time you need the police because their salaries are socialized by taxes. It’s an effective way to ensure quality of life for all citizens, with payments proportional to their income. Adding industries to tax socialization is an effective way to bring balance to capitalism, and improve the quality of life for vulnerable members of society, without the need of a full system overhaul.
If power remains with the capitalist class, and industry continues to be organized around their whim, you will not achieve meaningful reform, except in response to a threat, which will be taken away when that threat diminishes. FDR didn’t do the New Deal because he was secretly had socialist beliefs despite his family, but because he was old money buying guillotine insurance.
I was clarifying the difference between checking capitalism with socialism, and a socialist economy. You seemed to think socialism cannot be integrated into capitalism. Did my explanation help you understand the difference now?
What you are describing is social democracy, a subset of capitalism. That is not socialism integrated into capitalism, because once again, power remains with the capitalist class.
Socialism does not need to be regulated by a government. It’s a form of economy. However, we currently socialize many industries in a capitalist nation, and by socializing more industries, we can improve the lives of poor people at the expense of the wealthy, effectively keeping capitalism more equitable.
It’s okay to be a social democrat, buddy, welfare states are perfectly acceptable forms of ideological liberalism.
One might even call it a step on the path to actual socialism. Someone should write a book about these transitionary states, perhaps leading to the eventual withering of the state entirely.
