It seems that an “almost” industrial revolution happened around 500BC. For example, this graph of estimated world population shows a population jump then similar to the start of the ~1800 jump. Also, consider this brief history of the Roman Empire:

~5 century BC: Roman civilization is a strong patriarchy, fathers … have absolute authority over the family.
~1 century BC: … Material wealth is astounding, … Romans enjoy the arts … democracy, commerce, science, human rights, animal rights, children rights and women become emancipated. No-fault divorce is enacted, and quickly becomes popular by the end of the century.
~1-2 century AD: … Men refuse to marry and the government tries to revive marriage with a “bachelor tax”, to no avail. … Roman women show little interest in raising their own children and frequently use nannies. The wealth and power of women grows very fast, while men become increasingly demotivated and engage in prostitution and vice. Prostitution and homosexuality become widespread.
~3-4 century AD: … Roman population declines due to below-replacement birth-rate. Vice and massive corruption are rampant. (more; HT Roissy)

Yes this exaggerates, but the key point remains: a sudden burst in productivity and wealth lead to big cultural changes that made the Greek-Roman world and its cultural descendants more forager-like than the rest of the farmer world. These changes helped clear the way for big cultural changes of the industrial revolution.

These cultural changes included not more political egalitarianism, but also more forager like attitudes toward alchohol and mating:

Historically, we find a correlation between the shift from polygyny to monogamy and the growth of alcohol consumption. Cross-culturally we also find that monogamous societies consume more alcohol than polygynous societies in the preindustrial world. … Studies find a positive relationship between alcohol use on the one hand and a more promiscuous and high-risk sexual behavior on the other hand. … The Greek and Roman empires … were the only (and first) to introduce formal monogamy. … Hunting tribes drink more than agricultural and settled tribes. … Hunting tribes … have more monogamous marriage arrangements than agricultural tribes. …

The emergence of socially imposed formal monogamy in Greece coincides with (a) the growth of “chattel slavery” (where men can have sex with female slaves) and (b) the extension of political rights. … The industrial revolution played a key role in the shift from formal to effective monogamy and in the sharp increase of alcohol consumption (more; HT Tyler)

This roughly fits my simple story: forager to farmer and back to forager with industry. The key is to see monogomous marraige as an intermediate form between low-commitment feeling-based forager mating, and wives-as-property-for-live farmer polygamy. Let me explain.

Forager work and mating is more intuitive, less institutional. Mates stay together mainly because they feel like it; there is more an open compeition to seduce mates, and there’s a lot of sneaking around. Foragers drink alchohol when they can, and spontaneous feelings count for more relative to formal commitments. The attitude is more that if you can’t hold her interest, you don’t deserve to keep her. Men show off abilities to obtain resources mainly to signal attractive qualities; most resources acquired must be shared with the rest of the band.

Farmers, in contrast, don’t share much, and are far more unequal in the resources they control, by which they can more directly “buy” wives. Farmer wives so bought are supposed to be committed to their husbands even when they don’t feel like it. Marriage was less about mutal attraction and more about building households and clans. Husbands worry about cheating wives, and so try to limit access and temptations, which includes alchohol. Musicians and artists are also suspect if they excite wives’ passions, which might lead to cheating.

When empires like Greece and Rome achieved sustained periods of prosperity, their elites reverted to more forager-like ways. They had more drinking and art, more egalitarian politics, fertility fell, and [non-slave] mating became more egalitarian and about feelings. If a bit of alchohol was enough to get your wife cheat to on you, well maybe you didn’t deserve her. The Greek-Roman move from polygamy to monogamy was a move in the direction of more forager-like feeling-based mating, though it retained farmer-like lifelong commitment.

The Greeks and Romans became models for Europe when industry made it rich again. In our era, fertility has fallen far, divorce and out-of-wedlock births are common, and alchohol, drugs, and sneaking about are more tolerated. Women need men less for their resources, and choose them more on other grounds. Dropping the lifelong commitment element of marriage, and often the expectation of any sort of marriage commitment, we have moved even further away from farmer wives-as-lifelong-property and toward forager “promiscuity.”
