In my search for a bike, I've questioned where they are made -for many reasons (labor issues, environmental, social, etc). Can others add to this list?

Here's a partial list of where bikes are made, with the caveat that this is the info I could gather for CURRENT bicycles (many of the locations have changed especially in this decade), but the accuracy can only be confirmed thru the honesty of the companies. You will find many of them have deceptive or elliptical explanations on their websites.
