union membership is a way to get cacs. the right is extremely hostile to unions, the left has its head up its ass, and the center has been willing to throw them under the bus when pleasing certain interests, thus, union membership keeps declining.
addressing economic anxiety wont make someone less cacish, but it can create enough opportunity for them to vote for material reasons instead of merely voting to "stick it" to blacks/queers/etc.
the biggest civil rights victories happened when union membership was higher while cacs were much more hostile. the south never had high union membership for this very reason - to prevent cross racial solidarity. the midwest is where cacs and blacks ended up having material interests in common due to the high union membership. even today, the rust belt can swing to any candidate, red or blue, even with all those cacish people.
