Indeed; £55k is well over median UK income. I’m quite a senior software engineer in the UK and I don’t earn anything like that — forget about £70k! That’s because I don’t work in finance and I’m fine with that. The hedonic treadmill is not worth getting on, imo.
Yeah London is kinda the outlier with this. Give me that pay in say Cardiff and I wouldn't really have anything to complain about money wise. I could be happy slowly getting pay rises collecting my mountain of gold.
