Everyone is highly private about their?accomplishments?and failures. Someone's performance in any field is their performance alone. This is different compared to India where people flaunt their riches and share their accomplishments with everybody else.

Rich people are thin/ well maintained, poor people are fat. This stems from the fact that cheap food is fatty, rich people don't eat cheap food — they tend to eat either home-cooked food which is expensive or eat at expensive / healthy places. Unfortunately, it is expensive to be healthy in America.

Fat people are not respected much in society. Being fat often has the same connotations as being irresponsible towards your body. If you're thin (and tall, but not as much), people will respect you a lot more and treat you better. You will also receive better customer service if you're well maintained. This extends my previous point which mentioned that if you're thin, you're statistically likely to be rich. Reason why I know this is that I went down from being 210lbs to 148-150lbs. The way people started treating me when I was thin was generally way better than the way I was treated when I was fat. As a small example, the Starbucks baristas were much nicer to me and made me drinks with more care.

Almost every single person in America has access to basic food, clothing, water and sanitation. I haven't been to states like Louisiana and cities like Detroit, but from what I can tell, nobody is scrambling for the basic necessities required for sustenance.

Americans waste a lot of food. It is very easy to buy in bulk because it's so much cheaper and as a result a lot of wastage occurs.

Obsession with coffee — Starbucks, Dunkin' etc is crowded with office-goers and students every morning. I don't understand why they can't drink or make coffee before leaving for work. Such a waste of money! ($5/day * 5days / week * 52weeks/year)!
