The US GDP-per-capita (adjusted for purchasing power) [1] is only somewhat higher than highly developed European countries.
Given the relatively small GDP gap, the differences you are seeing have to with different cultural and therefore political priorities around spending on public infrastructure and social goods like education and job training. Different as in less.
Also, a lot of the US pattern of production and consumption is based on premise of disposability (with the notable exception of some infrastructure built leading up to WWII).
That has an effect on the durability and perceived quality of the things you see and experience in the US.

The two closest countries to America in this category are Australia and Germany, and a trip through Berlin or Melbourne won't make you particularly excited for the countries' infrastructure.
The US is an extremely natural resource rich country as is Australia which explains a lot of the difference in GDP per capita.
Germany is quite a bit behind the US in GPD per capita, much closer to the UK and France than the US.
One thing to remember though is that the way GDP is calculated means that selling the same service for a higher price leads to more GDP so it's a very imperfect measure.
Also, when in the U.K. I thought "everything is so small, can't they afford better?".
Of course I know neither of those is true.
Maybe it's cultural bias, but I find American hotels of significantly higher quality dollar for dollar. Same goes for food, except for some of the European countries with rich food cultures.
US airports are pretty shitty. I wonder why? Maybe they are older on average?
Also if you are primarily visiting NYC, its sort a shithole by American standards. The hotels are tiny and ridiculously overpriced.
Also, per capita GDP is comparable or lower than parts of Western Europe, which will affect how nice/poor it looks.
It closed out 2017 near $59,000 for the US. That's nearly 70% higher than the European Union's GDP per capita.
Germany is around $42,000. Austria $44,000. Finland $43,000. Netherlands $45,000. Belgium $41,000. UK $40,000. France $38,000. Italy $30,000. Spain $26,000.
Denmark and Sweden get the closest otherwise at $54k and $51k.
To put it into further perspective, France, Italy, Belgium, the UK would be among the poorest US states on a GDP per capita level, comparable to West Virginia and Arkansas.
The US problem is allocation of resources. $200+ billion should be chopped right off of the military budget and redirected to infrastructure. Another $100 billion could be redirected for infrastructure by altering war on drugs / policing policies.
$300+ billion extra per year into US infrastructure would result in the US having among the best infrastructure on the planet.
