Its not toys. china makes that. not cars, japan makes that. It certainly isn't oil as we all know where that comes from.What do u think is the no.1 US export that only we produce and no one else? as wild as it may seem the only thing i can think of as proudly USA is porn.

I have no idea what it is, but I might lean towards software. Think about how many computers use Microsoft Windows.

WeaponsNuclear MaterialFarm Equipment (John Deere and such)

I would say it is the US dollar in the form of investment foreigners make.

The number one type of export for the US economy is consumer goods, which accounts for 49% of total exports, or US$501.8 billion. Consumer goods refers to any goods for consumer consumption (so not military firearms like someone mentioned), from pharmeceuticals to dishwashing liquid. The top export product is unlikely to be known, as corporations go to great lengths to protect commercially sensitive information.

pain!
