oh i remember that meat boycott---as i recall, many housewives tried shifting to fish, non-meat dishes or less expensive cuts of meat, and a lot of that new food wound up uneaten in the trash because family members hated the taste of the new stuff
anyway, that meat boycott was shortly preceded by the Great Grain Robbery. The USSR had a major harvest failure in 1972 and was able to keep that a secret. So the USSR bought grain in 1973 at prices that presumed a normal harvest --they covered their shortage. When the news got out about the actual supply available food prices around the world rose...in 1973 prices around the world were up 30% over 1972 (wheat is a feed for livestock). The strange part was US citizens had paid farm subsidies to farmers to produce wheat that wound up being sold at below fair market prices to the USSR.
Shortly after this Grain Robbery, the US launched spy satellites that allowed for monitoring of USSR farm production. If the satellites had been available a few months earlier, a better price for US grain sellers would have been gotten...but I don't think that better sales price would have been passed through to American consumers--nope, it would have gone to grain brokers who then would have given a cut to politicians (because that's the American Way).
