Democratic Primaries

The reality out there is that those lofty goals are not actually how things work. Any of those characteristics you listed can block opportunity for anyone who exhibits them in the face of prejudice. Can and does.

While it is possible to legislate equality of pay for work or even to limit the discrepancies of unfair pay differentials between line workers and management, it is impossible to legislate against prejudices effectively.

We do not all start with a common base of opportunity in society. Sometimes that's due to lack of education, but it is more often based on skin color, gender, ethnicity, sexual orientation, or other issues that should be, but are not, irrelevant.

You do not understand, possibly because you have none of those characteristics that hold people back. Perhaps you have unrecognized privilege and do not quite understand how that helps you in many ways. I don't know you, so I cannot say for certain.

I can, however see Bernie Sanders, so i know what his privilege is. I'm not sure he can see it, though.

Government cannot control prejudices. Those are purely social constructs. They are not really subject to legal manipulation.
