I honestly don't know what it takes to feed an infant now or in the past.
But what I do know is the 'supply chain' issue is just one symptom of a much more serious disease broadly known as Neocolonialism over seas or Neoliberalism here at home.
Over the decades the Neoliberals have chipped away at the powers of the regulatory oversight branches of the government from IRS to the CDC, FDA, EPA, BLM, SEC, HUD, HHS, EDU, USPS, DOL or name any other agency you can think of besides anything to do with the department of defense, if they couldn't directly take power away they just take the funding away. One_little_bit_at_a_time, year after year after year and giving the 'savings' to their bankster and monopoly lobbyist friends from K Street. After all would you rather own a casino? Or a government?
Yeh, welcome to gangster Capitalism at it best it'll all be so much better after everything is once and for all privatized.
