According to Davos it seems that China will be No1 (double GDP) by 2030:
GDP is smokescreen data, that much we should all notice.Its a system data showing how a country is doing. Acording to GDP Russia is doing fine.
US of A is doing fine too, and most countries give cleaned data to the "authorities" who like to sample those. Davos known as being worker friendly.
No doubt that the upper political class is doing just fine.
For better or worse, GDP is the best metric to compare capitalist economies...
There are also other metrics, such as the Gini coefficient, but I don't think it's better to live in Cuba compared to USA, despite having "free" healthcare.
