These “social democrats” proposed that democracy could protect the things that should be shared in a society, such as;

-healthcare
-information
-the environment
-and even markets

Yup, even capitalism can be socialist if you accept markets as

natural human expressions

“Social capitalism” can be considered a market economy with oversight by the affected parties. Remember, socialism is just the concept of a general welfare beyond

individual greed

The use of authority required to uphold these ideologies is where they separate.

For example,

zombie libertarians

might care more about protecting their property than improving society.

It is all about what your values are; personal liberty or the social good or (just maybe) a healthy mixture of both.
