I left the UK after graduating at 21, fully intending to come back within a couple of years. Its weird watching it from the outside for 10 years waiting for a "good time" to move back and realizing that time isn't coming more and more each year. The salaries in Japan arent great honestly, but mine, the quality of life and how far my money goes is so much better than if I lived back at the UK. Every time I go back it…
IMO the UK should look at what Singapore did and maybe learn from that. There's really no excuse for a country like the UK other than ordinary plain and simple mis-management from the top. Singapore did not depend on neighboring countries to climb out of 3rd world poverty. To name an example.
To maintain its wealth today, Singapore relies on a large underclass of underpaid non-citizens. Around 40% of the country are non-citizens.
In addition, London sort of has its own Singapore(s) in the form of the City and Canary Wharf. That's great for those who work there, but it's not feasible for a country of nearly 70 million for everyone to just work in finance.
Final comment:
> Singapore did not depend on neighboring countries to climb out of 3rd world poverty
Singapore's wealth is built on trade and foreign investment. To assume that without other countries it would be equally successful is absurd.
