… do they eat more?

I would have thought once a week is high.

Though median could differ from average. 12% of Americans eat half the beef

Average American eat around 60 pounds a year, typically you eat less than a full pound when you eat so yeah they probably eat more than once per week.

Given the $112 subsidies per year above, that would add $2 per pound of beef, that would slightly raise the price not balloon it to 30-40 as poster claimed. So he was bullshitting.
