Like anything else you can find all ranges offered and all ranges accepted.
I thought the exact opposite was the norm, with higher rates in US companies than UK/europe.
Senior level rates in US range from 100-300/hr. I know it's a big range, but it comes down to speed, creativity, references, portfolio, fit for the project, availability.
As far as the half the money as a 9-5, it's actually the other way around-- as a freelancer, you need more money to compensate for things like insurance, taxes, risk that come with being an independent/freelancer. So they say to match a 75k salary, you need approximately 150/hr.
