Is Africa better off now than during the Colonial period?

Answer 1

No, but many of the current problems may be attributable to the colonial period.

Answer 2

Africa is a huge continent... some parts are better off, but some aren't.

Some parts are still colonized, for instance, Morocco has invaded Western Sahara, and the government of Sudan is brutally repressing a lot of people who want independence.

Kicking out the European governments doesn't mean the colonial period is over.
