I think that's evident in the Bernie Sanders movement (and to a lesser extent, Warren). Folks like myself support him even though we're some sort of "upper middle class" or some form of middle-merchant class. Not owners, not truly capitalist/investment class, but solidly aligned with everyone else who also has to show up at 9AM daily to get their checks.
This more affluent middle class of information workers are leading the rest of the folks who punch a clock for a living to a better life. It's not everyone though, there's older folks who are fully committed to a dog eat dog existence, because it worked out easily and well for anyone willing to even try their hand in the post-WW2 era. It's understandable that they don't see the connection between relatively easy prosperity, and destroying all of your industrial competitors. Some of the younger conservatives don't have the life experience of being exploited and tossed out to form well-informed views on labor, and are often afraid of challenging their tribe's view, with their fathers often being the aforementioned Boomer. Then you lose another chunk from those who are not very capable, but inherited wealth. Insecurity that they couldn't duplicate their position in life from scratch leads to extremely anti-social behaviors that we see from the capitalist class.
Claiming some defectors from each of those groups, add in the blue collars who know the score, and add in the "Bernie Sanders" educated folk and I definitely am seeing more support for the movement in American society today than I do for any other grassroots movement. Judging from the strength of support of someone like Sanders, the only competent base of support that rivals it is Trump's. It may not be tomorrow or next year when it succeeds, but we're definitely seeing what you're describing and I suspect it'll continue to build until big money can't stop it any longer.
