Low prices are probably most important to people who are trying to live on savings or unemployment benefits while they find work. Even so, most Americans have jobs and they like Wal-Mart because shopping there saves them money, so they can get more bang for their buck. I don't know why some people have a problem with that. I suspect Sam would never have been caught telling his customers they had to pay higher prices to support some union or a company that couldn't compete.
Maybe you could ask big government to force all Americans to pay higher prices for all goods, not just those found at Wal-Mart, so that there would be more jobs. It's our collective duty, after all.
Are you just dense? Yes, I would pay higher prices to keep Americans working rather than some Chinese in a foreign sweatshop.
