Instead, they got slavery, colonialism, multinational corporations, foreign installed puppet governments, debts, modern slavery, outside financed extremist groups and civil wars, ...

Just try to look objectively, and you'll see that a vast majority of people in Iraq, Libya, Iran, and Afghanistan lived much better and safer life then after a series of foreign interventions and introduction of "democracy".

If we go a bit further in the past, the whole population of South and North America got annihilated by the diseases that came with the colonial forces. So yes, they would definitely be better if we had a Star Trek approach.

The myth of the good savage conveniently forgets that most, if not all of this things were present yet in spades in the primitive societies, with other names, but not so different in fact.

And people in those countries also live a safer life with modern medicine, airbags, concrete in buildings, modern roads or telephones that they don't developed. You can't take just the good parts of modern societies while claiming that those societies are evil and refusing to improve them. This is just hypocritical.
