If there was an easy way for a developed nation to post 4% GDP growth rates, I’m sure at least one of them would have done so by now.
Many western nations have lower GINI coefficients and higher minimum wages, but their GDP growth rate isn’t much higher.
Australia has a Gini coefficient of 35 and a minimum wage of $15, while the US has a Gini coefficient of 46 and a minimum wage of $7. Nonetheless, Austraila only posts GDP growth rates of about 2-3% like the US (their per capita income is about the same). Western European nations have lower rates of inequality and higher minimum wages, but their GDP growth rates are not really different than the US.
Looking online, some OECD nations are posting those rates though.
Israel - 4%
Ireland - 5.2%
Iceland - 4%
Some of those numbers may not be accurate, different sources say different things.
Either way, I’m under the impression that to post truly impressive GDP growth rates you have to be a developing nation that is absorbing and utilizing a lot of developed nation technology for the first time. This vastly increases the human capital and ease of doing business in a nation.
A nation with a per capita GDP of 4k may not have good roads, health care or education. Businesses may not use any tech, but as they grow they’ll pave roads, invest in education and health, businesses will adopt best practices, etc. and GDP growth rates will be 5-10% a year because going from a society of illiterate, sick factory workers doing everything by hand to a society of educated, healthy workers using robots vastly increases productivity.
Because wealthy nations don’t have a ton of new technology they can adopt or investments they can make to increase human capital (because they already use the best tools the human race has at the moment), they can’t post those kinds of growth rates.
