I strongly disagree on the causality here. The red state subsidies are a blue team talking point. To the extent the reality gets through to the red team, it's anticonvincing because the main thing they feel they're missing is self determination.
Telling them to be appreciative of federal welfare, and they can get even more of it (eg UBI), is the exact opposite of what they want. They want purpose, hence the attraction to regressive ideologies promising that there is purpose to their suffering. Purpose cannot be provided by overt direct subsidies - it can only come from the feeling of earning one's way, regardless of the truth of the matter (eg how the metagame industries suffice). By extension this means revitalization of rural economies, no matter how artificial. Then again after decades of ZIRP what does "artificial" even mean?
