But then again how much do you earn to pay that tax and NI? It's a nice amount to get that much tax, I'd say over 35k

TBH the I'd say our tax is not that bad of a system even if it is a rip off (tax always is), but the grass is not much greener on the other side either, there's always pro's and cons even in other countries that are over the sea, you win some you loose some.
