"Chauvinism" isn't incorrect, but a very loaded framing. Conservatives believe that culture is of overriding importance to the prosperity of a society, and do not embrace cultural relativism.
What makes the United States rich and Bangladesh poor? A liberal would immediately go to explanations involving colonialism, etc. A conservative is much more likely to go to explanations involving bribery, political corruption, etc. Liberals tend to be cultural relativists, so they perceive those cultural explanations as being "chauvinist" or "racist." But there are plenty of Bangladeshis who would give the same explanation. Among other Bangladeshis I know (I'm from the country), especially ones back home, they're much more likely to blame cultural/political institutions rather than colonialism.
