You don't seem to realize one thing, and I keep repeating myself. It's not that difficult to see if you just go and look. What you call Western accomplishment is built with the help of non-Europeans, at all levels. The West, as it looks today, is far from purely European. You were literally claiming superiority over non-European tribes, not realizing that you miss-attributed a very significant portion of these accomplishments.

Basing your worldview on a falsity is not going to help you in the long run.
