Disposable income per capita is high relative to Europe. Prices are relatively low (at a cost, food is one of the highest inflation categories, meat highest within that...I still don't understand how chicken is so cheap, animal welfare is generally high...but it just shouldn't be this cheap...same thing with vegetables, retail is so consolidated that farmers have been getting short-changed for decades). Generally, it is good to be a consumer.
The issues that the UK are similar to a lot of developed countries just worse, and made worse by unusually bad govt interventions over decades. The frustrating thing about the UK is that a lot of the hard stuff is done well but it is just thrown away by nonsense policy in other areas (i.e. we have a great tertiary education system, and absolutely horrible primary/secondary so relatively few Brits can actually get value of more education...it is just nonsensical)
If planning/housing was solved conclusively, it would resolve 75% of the issues impacting consumers.
