Most of the west got rich off oppressive tactics, i.e. slavery in the USA, exploitation of the resources of weaker, resource rich countries in Africa, etc. Keep this in mind, when you praise them and ill gotten wealth is bound to perish.
It's like hey, that guy got rich from exploiting the poor and not paying taxes, and other illegal stuff; wow he's so cool! [an analogy here]
Who said that? Being ''modern'' doesn't mean we have to praise things that are immoral and unjust, we can have the societal advancements without compromising ourselves as Muslims-yes, in this case, one can have their proverbial cake and eat it too.
You are focusing on individuals, who are wrong at times, and right at times, while not focusing on the deen, the actual truth, that's the problem I see with you here. You can raise your kids in the west, that's fine, but do not complain when your daughter has boyfriends, doesn't cover up, smokes, drinks, parties, etc, and when your son is the same; I've seen it here in the West. Muslim girls with boyfriends, who don't pray or cover, etc, while the men are equally as bad, doing the same sins. Is that really better than an Islamic environment, even if it's poor there?
Yes, or no, depending on your perspective- if the dunya is all you're after, sure, it's better in the west, if the akhirat is what you prefer, while seeking good in your share of the dunya as well, then....
