Why are americans like a spoilt rich kid and think they are best?

Are they best at:

Healthcare system - NO

Inflation and economy - NO

Technology and AI now - Not anymore, there is China too

Education - NOT AT ALL

Architecture - NO

Politics - NO

Justice - NO

Weapons or nukes - There are russians too

Social government - NO

Hollywood and movies - NOT anymore, only woke bullshit

Welfare or educated calm society - there are much better european countries

So why do still americans think that they are the best in the world. No. There is no one single thing they are best at anymore. And they collected the hate from all over the world because they started lots of fights. They killed even engineers they can not compete with. And they finally started losing at everything.
