Out of curiosity, why would an American worker vote for a democrat? To get a Bronze Plan? To have no seat at the NAFTA table?
While examining the important differences between the plans in the chart towards the middle of the page, it is important to remember that this is the difference democrats bring to the table in terms of actual lived experiences for working people. The table highlights wonky specifics and continuations of the current system that all look the same in the wash. For working Americans, it is very difficult to see any substantial difference between the two parties. However, there are very large culture differences between the two which conveniently keeps the working class divided.
In fact, the only big legislation I recall Republicans passing in my lifetime is lowering taxes for some people and the Patriot Act/Homeland Security nonsense.
I do think the parties are good at delivering cultural signals. Neither of us can readily point to substantial policy differences, but we know deeply the cultural difference between truck nuts and vegan lattes, for example. We also know, without being told, the difference between welfare queens and cis white males. I think the parties offer this kind of "satisfaction" for their voters.
Democrats are at least not outright denying climate change. Investments in green technology could bootstrap an industry for unskilled workers that cannot be offshored to foreign countries. Even if you are not employed by these industries you would still see the general benefits of hitting 2% inflation targets which decreases inequality in the long run.
