Short answer: Yes, I'ld pay 10% more for equal quality if it was Made in the USA.
Long Answer: We live in a global economy, and it's very hard to get anything that is 100% made in the USA. So I'd like to get some idea of where the content comes from, and just what work was done on the product in the USA. For example, "Driveline from xyz", "gear box from xyz", "Steel from xyz" and "All cutting of steel, welding, and painting done in the USA". Also tell me where it was designed so I know where the white collar jobs are. So rather than just rely on a "Made in USA" sticker, why not also take a paragraph or two and tell potential buyers the details that will help them make a decision. You are not selling $2 socks, you're selling expensive implements and people will take the time to read a paragraph or two.
Note also that post-sale support is as important as price.
Comment: It's probably easier to get implements with substantial USA content. If electronics are involved, there are very few chips, semiconductors and other components that are manufactured in the US. But there are a lot of circuit boards and assembly work that is done here. The best Apple computer can do is a "Designed in the US". So some things are easier to get high US content than others.
A global economy is good for everyone, but it has to be a two way street not the one way outsourced mess we have today.
I buy the "cheap stuff" when I plan to use it at 1/10th of it's rating or when I've thrown my hands up on finding or being abel to figure out if what I'm looking at is of good quality or not. If you can't tell you cover your bets by buying cheap. It can be hard to tell if the extra money you paid went into the product and worker wages or into the marketing and profit. Sometime extensive marketing and distribution is used to sell something rathe than re-designing the product so it's right.
