You can go back even further, to the 1970's. Look up the "Rust Belt" of America. That's when all those single-income factory jobs were destroyed because the owners could save a few pennies pulling up stakes and moving the entire company overseas. Company owners got to have their sweatshops while America switched from a manufacturing nation to a retail nation.
This deepened the rot of feminism because oops retail doesn't pay nearly as well, so it increased the demand for two-income households, which meant fewer stay at home moms to properly raise the kids, etc.
