>why the countries like uk canada and also Europe are incredibly poor

They are not that poor if you adjust for cost of living and hours worked. If you look at the Wikipedia thing "GDP per working hour (2019 US$ PPP)" some results are:

Denmark 76

USA 74

Canada 57

Spain 56

UK 54

So the pay isn't that much worse per hour. People probably work a little less over here, maybe because we don't have the whole if you don't work you won't get health cover and will be doomed thing.

Also life expectancy is 76 years in the US vs 84 years in Spain. There's more to life than working all hours then croaking.
