Protestant countries like Zimbabwe, Congo, Malawi, Namibia, Papua New Guinea, Rawanda, Swaziland, and Tuvala?

A child can see through this answer..

Just at a glance, The Congo is about 50% Catholic with the rest being native and Protestant religions.
Rwanda (bloody Rwanda) is majority Catholic,
Zimbabwe has religions that try to mix native belief and traditional Christianity as the majority.
Malawi has Catholics and Presbyterians as the majority religion. Malawi also has a history or religious persecution.

Anyway, that's enough to show whoever made that list doesn’t know what they're talking about.

(Some of the information came from CIA Factbook on each country.)

Then get a child to explain it to you because it is as fair a comparison as your suggestion that underdeveloped Catholic countries are the fault of the Church.

The truth is that largely Protestant sub-saharan Africa is the most destitute and hopeless place on the planet. Like Latin America and the Philippines, that is not the fault of any religion.
