Firstly, that it is illegitimate to criticise capitalism because it has created some benefits. As if we're not even allowed to dream of system reform because we're currently doing better than other countries. Very little social or economic progress would be made if we all thought like this.

Secondly, that those benefits are purely due to unadulterated capitalism. In reality, Western countries follow a mixture of capitalist, statist, and socialist policies. The poor in the US have seen improvements because of the minimum wage, anti-trust regulations, and various social safety nets combined with economic growth.

Thirdly, that the only thing holding other countries back is "their own cultures". This ignores widespread, long-term destabilising interference by Western countries in Africa, the Middle East, South Asia and South America.
