Progressives and leftists have tons of literature out there on the policies and ideas they want implemented to improve society, just because you haven’t bother to look up any doesn’t mean it doesn’t exist.

As to how that gets implemented again it’s out there but going to depend on what country and topic we’re taking about if you want someone to provide something specific.

More than happy to provide some but given the post was on “leftist discourse” I’m a little unclear on what specific topic you’re unable to find the leftist position for here.
