Nevermind the abundance of evidence that it is true. Surviving women who lived under communist rule and capitalist rule overwhelmingly report that, that was the one really good memory they have of it. And that their sex lives were far more satisfying then than it is now (and way more so than what their daughters report now). Sexual satisfaction is the single most accurate proxy for measuring gender equality.
Even today the most gender equal society on earth (Iceland) reports the highest level of female sexual satisfaction. By a massive margin.
