I think you are greatly over-estimating how many people would be willing to pay the cost of a North American made toaster. This would require an absolute ton of capital to do it on anything above a craft scale. The challenges of design, testing, certification (very important for a device that could burn your house down), manufacturing, supply chain, and support that are all specialized careers in themselves.
I've got more than decade of experience in designing products that are built in North America. I wouldn't touch a project like this unless it had a team of people with the proven manufacturing experience heading it up and some very convincing numbers about the commercial viability of the product because I don't believe they exist. There is good reason why the market only has commercial kitchen grade devices available.
