In the US, millet is grown almost exclusively for animal feed.

Many of them, having "made it" socioeconomically, focused on white rice to the exclusion of "lower class" options.

For example, the first written record (Tacitus) we have of the Germanic peoples (farmers who used livestock heavily) claims that the men did nothing but prepare for and engage in warfare: all the farming and taking care of the livestock was done by the women.

(And when wheat farming and livestock-keeping were introduced to Britain, after an initial enthusiasm, many went back to fishing and gathering chestnuts. This was prehistory so there is some uncertainty about this.)

In fact, pretty much the whole history of farming has been that you farm the land of someone who will protect you.

the socialist impulse is still alive and well in the Americas!
