Agree 100% with OP.
I am not aware of any country which would qualify as a country B.
Someone knows a country like that ?
Hong Kong had relatively low income and capital gains taxes (under 20%), and raised 1/3 of government revenue from land tax (basically like a property tax but only on the underlying land value). Went from 3rd world to one of the richest places on the planet in about 40 years, despite no natural resources. Singapore had a similar thing.
No one would argue that Singapore and Hong Kong under the Brits were unsafe places, lawless, or insecure - in fact the crime rates were lower than in the west.
Therefore it has been empirically proven beyond all reasonable doubt that you can have law-abiding, peaceful, rich countries sustained by a tax rate of below 20%. W Europe and USA, with much greater advantages in natural resources and defense, should be able to levy even lower taxes, maybe 10-15%.
And that assumes Hong Kong/Singapore had the ideal tax rate & spending rate. Arguably they would have become even richer had government spending and tax been even lower.
