So while they can see the issues as you’ve described them, they won’t breath life into your movement but sap away its energy for their own interests.

Is this based on real present day material conditions, or is it a hypothetical based on historical examples? While I don’t think we should ignore those examples, it’s also important to recognize that things may have changed, and groups that may have previously been part of a prosperous middle class no longer feel as happy and secure as they once did. I’m not saying we should feel especially sorry for them or focus on them at the expense of groups who have it much worse, but I just think it’s not productive to ignore them completely or even brand them an enemy.

The lifeblood of historical communism was in unskilled labor, poc, migrant workers, and the rural poor who were the most effective organizers.

I don’t disagree with this and it makes sense that more activity would happen where the need is the greatest. However, I do think that it can be problematic when folks on the left see this solely through the lens of moral alignment, as it would tend to lean toward a poverty fetish and “white savior” type mindset where people are primarily concerned only with having the morally correct position. This sort of thing seems somewhat common across the western left, especially online.
