Bearing in mind that 30k a year goes a lot further given that there's no need for health insurance and student loans are effectively just a 6% tax on earnings above 27k until either your loan is repaid or it's been 30 years since graduating.

While it's true that UK salaries are quite a bit lower than other countries if I'm honest if I earned £150k a year the only difference in how I live my life would be that I'd be driving a Tesla. 30k is more than enough to live comfortably on, even in areas with a fairly high cost of living.
