My dad moved to the US in 99 (he grew up in a town of about 50k people at the time). He said he was shocked people would stop for him when crossing the street, and he was amazed he could by a 1/2 gallon of ice cream for a couple bucks. Previously, he might have had ice cream once a year. He was also impressed and made happy by the abundance of meat and milk.
Funnily he was quite disappointed at the fruit situation coming from a tropical country, but that was more about freshness than quantity.
There's also the issue that people from tropical countries are used to a variety of fruit we simply don't have. There are various things that are either rare in the US or completely absent because they can't survive being shipped. Even subtropical--my wife loves dragon fruit but is unwilling to pay through the nose for the very inferior stuff in the market here.
While I do not have a taste for tropical fruit there are the bananas we encountered in Africa that ruined me. Since encountering those I have pretty much zero interest in US bananas, what we had there can't be bought in the US because they don't ship well.
