Blue states do NOT subsidize Red states. All those articles are ignoring the #1 reason by far that Red states get more fed money: Red states are friendlier to the elderly poor, so elderly poor choose move to Red states, and so all their Social Security payments and Medicare subsidies are counted as Blue money moving to Red states. Your criticism here ignored this fundamental reason, because when you realize this fact, your whole Blue states subsidizing Red states schtick becomes patently absurd.

And the reason Red states got more corona money ---per taxpayer — is because each taxpayer got more money for more children and conservatives have more children https://link.medium.com/ZJlgT3Ibktb
