The lack of "Made in the USA" products annoys me

It really annoys me that America, once a worldwide leader in manufacturing of
all types of goods, now sells so many things made overseas.
Today, I went to Old Navy to buy a sweatshirt, and to my dismay, everything I
looked at was made elsewhere, Bangledesh, Indonesia, China.
This has got to stop.
I know how it happened, but if we keep this up we lose big time.
I remember watching a report on TV not to long ago about how the USA was once
the worldwide leader in tee shirt manufacturing.
Now, we make virtually none of those common items here.
Sure, I can go to American Apparel and get American made products. I like the
stuff they make. But sadly, they are a brave face in a growing world of products made in
far away places, that pay their workers horrible wages etc.
How do we stop this?
Is it too late?
