Reiki healers and homeopaths are listed under code 3214, "Complementary health associate professionals".

And I only picked those two because they were particularly egregious. The list is full of jobs for which it's absurd to suggest we need to fill from abroad: are we really suffering for a lack of recruitment consultants? Human resources officers? Can no-one can find a homegrown Brit who's able to work as a restaurant manager?
As for the salary threshold, you're right: the basic threshold is £41k, although it can be as low as £25k (not £33.4k) in some circumstances: https://www.gov.uk/government/publications/skilled-worker-vi...
I'd argue that £41k is still too low. It's barely above the median UK salary - we can't find anyone in the top ~50% of people who can do these jobs? And it doesn't even make you a net contributor (from what I can tell that threshold is around £50-55k, although for many of these "skilled" workers it's much higher as they bring dependents.) Nevertheless I'll accept a partial L.
Regarding English, maybe I'm wrong about the precise requirements, but I've worked with software professionals in London, here on a skilled worker visa, with whom I was barely able to communicate, so clearly we're doing something wrong.
In any case, my thesis still stands: there have not been "very high" criteria to migrate to the UK recently, in fact quite the opposite, and if you don't believe this then I suggest you go outside and look around.
