Give me 1 good reason for not always buying American and living/travelling only in the USA all of the time...?

Because I'm English.

Adventure.

I believe in traveling the US, but, it's almost impossible to only buy US made things.

Because we dont actually make anything here anymore pal, dont you ever look at the labels of what you buy?

People used to be upset at the Japanese, but they only sold cars and consumer electronics here, the fucking Chinese make virtually every product in every store in this country.
Jut try to find something made in the USA, it's impossible.
