> Do you think those non-techies are sympathetic to the Microsofties and Amazonians?

As somebody who has lived in Seattle for over 20 years and spent about 1/3 of it working in big tech (but not either of those companies), no, I don't really think so. There is a lot of resentment, for the same reasons as everywhere else: a substantial big tech presence puts anyone who can't get on the train at a significant economic disadvantage.
