I’m saying Americans blame the west, not necessarily that Americans blame America. America had very little to do in the subcontinent, for example.
As to it being patronizing. Speaking for myself—I think if you can’t blame people for the state of their own country, you’re taking agency away from those people. The British did lots of bad things in the subcontinent and looted it. (They also left some really good values and ideas and institutions.) But that ended 70 years ago. In that same time period, South Korea went from being nearly as poor, and far more war torn, to being a developed nation. It’s not the absence of interference from the west that did that, it’s the industry and virtue of the Korean people. Likewise, to the extent Bangladesh hasn’t grown as fast as it should (and to be fair, things have gotten better at least on the economic side in the last decade), who is to blame? I think it’s patronizing to continue to blame the west. Maybe blame the fact that Bangladeshis supported a military dictator for President, supported dismantling secularism, invited fundamentalism in from the Middle East, etc. Whose fault is it? Maybe it’s the fault of the clerks in the Bangladesh Supreme Court that demand bribes to quickly your filings quickly. If we credit Koreans for the development of their country, Bangladeshis must get their fair share of blame for what is happening in their own country.
