> Skills that pay well automatically rate higher on the prestige scale.
This is pretty true. Though manual labor usually has less prestige at equal pay.
> Skills that pay poorly are skills that can be easily provided by whoever
This is much less true. There are plenty of skills that require a master's degree level of learning but also pay poorly.

There are many more of such masters than the market needs, so the pay drops until Demand meets Supply.
Of course. But low demand doesn't make them unskilled, right? I'm arguing against the idea that low pay/prestige makes them unskilled.
You could even have extremely skilled, moderately paid, but still relatively low prestige. And top of the trades pyramid go to this category. Think of specialised welders, were you need both years of expertise and probably quite a bit of aptitude... And the job is no way unskilled, but still would have less prestige in general population than some simpler job more of white collar type.
