While lower salaries would decrease the amount of financial pressure on companies and could lead to more competitivepricesz, I don't think that that would be the correct avenue to walk down no.
I think the only real solution to that is to break up mega corporations and try to fund and subsidize local businesses.
Capitalism has been a blessing for everyone, even those clowns on lemmy.ml or other clown instances, but when globalization hit, it went downhill. Trying to promote local businesses again would - at least in my opinion - better the entire system, from wages to prices to work conditions.
