Friend, I don’t know where you’re getting the idea that you are experiencing more comfort than you deserve, when you aren’t able to get basic medical care. You and your family are not the problem here, nor even all of the people like you collectively, but the system as a whole, one you didn’t choose and obviously don’t support.
Yes, things are going to get worse here in the US. No way around that at this point, unfortunately. The next few years in particular are going to be ugly. But to the extent that you and yours suffer because of that, it is undeserved; you do not need to atone or balance some cosmic scale of economic justice somehow.
As communists it is not our goal to castigate people for their privilege, nor to murder everyone on the wrong side of some mysterious dividing line between proletariat and petit bourgeois. Our goal is to reorient the relations between the people and the means of production, to focus the economy on improving the human condition, and more broadly, to prove that a better world is possible by building it. There is no requisite amount of self-flagellation necessary to call yourself a leftist, you have only to work to advance the cause in whatever ways are within your ability given your material circumstances (including time pressures and mental health challenges).
In short, give yourself a break; you haven’t done anything wrong.
The article was published in 2019 (rather notably prior to the ratfucking of Bernie 2020, which shifted this very debate dramatically), so maybe we aren’t?
