Lack of good examples of countries that are successful without being capitalist?
Pretty ubiquitously non-capitalist countries have a pretty poor track record.
I often hear the phrase, capitalism is terrible, but it’s the least bad of the terrible options.
As an aside, I’m arguing here for capitalism, not billionaires. Supporting capitalism isn’t an endorsement of a complete lack of controls and safeguards.
Could also be a correlation due to people who actually get diagnosed with dyslexia/dysgraphia being more likely to live in places that are more affluent or with better mental healthcare.
That would tend to correlate with generally more accepting populations.
