Free college is progressive. Because the ROI would be incredible; the investment would be paltry compared to the return. For the record, I also think that privatizing Social Security is progressive, for the same basic reason (ROI).
I think the minimum wage needs to be higher, but it should vary depending on jobs & regions. I don't think a blanket increase is progressive.
Healthcare is crazily complex (and Trump wants gov't funded universal, btw). It's only progressive if costs are addressed in a very significant way, but a country like ours should have universal healthcare.
Paid family leave is DEFINITELY progressive. Again - ROI, as related to productivity and worker satisfaction. No brainer.
