I know that previous civilisations contributed to our knowledge, but surely it can't be denied that right now it is western countries making advances.
When everyone was panicking over Ebola I saw people posting "why hasn't the US made a vaccine".
I didn't see anyone saying "why hasn't Nigeria or Iraq made a vaccine"
In the case of social advances it is very much a matter of opinion which is 'better', but more freedom for the individual without fear of being killed by a mob of neighbours sounds like an advance to me.
People say "oh the west isn't better just because they have medicine that works, GPs and ambulances on call, warm homes, education, freedom of speech, trial by jury, innocence until proven guilty, Equality under the law for people of every gender or color, phones in every home and pocket, television in nearly every room, leisure time and activities to fill it. Cinemas, Theatres, Gyms and shops.
Did I mention shops? Food delivered to your door or visit a supermarket that's open at night. Aisles of fresh food from every country without rationing.
The west is certainly not more advanced, but inexplicably a lot of people are leaving their homes to move here.
