Just to be clear, when you say “socialized capitalism” you mean capitalism, but with a welfare state?
The system currently burning the world to death with no particular sign of actually changing course.
Tell me if I get off course but some bullet points:
Resources are not limitless.
Unrestrained capitalism always leads to consolidation of control over finite resources and exploitaton of other individuals.
Limiting opportunities for individual development is negative to the society.
Individuals in the society are a distribution of variable abilities.
So…
Governments role in a well regulated market would be:
Limit consolidation of resources by any individual providing equal access for responsible use.
Preserve resources by limiting and regulating their use.
Provide equal opportunity for all individuals to engage in the market.
Provide a support network for all individuals to allow them to take reasonable risks.
Pretty much my thinking, but it shouldn’t even be necessary to mandate “limit consolidation of resources”. We do need wealth to be attainable, as the driving factor of capitalism, however the other factors you list would have the limiting affect if they were implemented.
Also, one of the goals of such a government needs to be “for the benefit of its citizens”. Every choice of a well-run government to regulate capitalism needs to be “for the benefit of its citizens”, and most failures in actual governments are when they don’t follow this
