I seriously, seriously, doubt this. It goes hand in hand with the 'happy, loyal' servant willing to doff their cap and bend the knee as the master walked past.
Of course, of course....but there is no doubt that overall the working classes were better off in certain ways in the Keynesian mixed economy (1948 - 79, roughly), than they are in neoliberal economies, struggling to find zero hours contracts to pay unaffordable rents. Even if employers exploited their workers back them, strong unions existed to protect them. And lots of employers recognised some degree of responsibility for the welfare of their workforce. Cadbury's built an entire village for their workers to live in, something unimaginable now. Homelessness barely existed in the 1950's and 1960s to the point where sociologists predicted it would soon die out.
In some ways, your point proves how bad things have become. Now the exploited, alienated worker that Marx wrote about has become a privileged position, because the one thing worse than being exploited is not being wanted at all.
A lot of the rights people won in the UK were not the result of a revolution, but the labour movement, which is more of a long, hard struggle that ran from the later 19th century up until the power. The post-war settlement and welfare state was then destroyed with great relish by Margaret Thatcher.
The sex industry is as much, if not more, a consequence of capitalism than patriarchy. Think of it this way: however bad things still are for women, they are a lot more liberated than they were 50 years ago, yes? So in that case why has the sex industry expanded at a huge rate? Shouldn't it be declining with patriarchy? Quite simply, the sex industry is a form of commerce that fills the gap left by the destruction of the welfare state economy. Once capitalism finds it doesn't have any coal or steel to capitalise, it moves onto people - capitalising their desires and bodies. It's currently doing some very strange things like capitalising knowledge and data. It's like a big beast that will turn absolutely anything into a form of capital. The prostitute or cam girl is the archetypal gig economy worker of the 21st century. Yes, she's being exploited, but is she being exploited anymore than her boyfriend who is working at Sports Direct? And she'll be making more . money than him. That's not an apology for prostitution by the way.
