How dedicated? Not very
Any company, anywhere, is dedicated to making money for the people who own it. If Jim High wants $30/hr and Kim Lo is happy with $10/hr for the same job, guess who gets the job. Hell, it's not just companies either - if you wanted someone to respray your car or build an extension on your house, you go for the cheapest quote that'll get the job done.
Granted, there is also the factor of how good a job they do. But when it's a job like production-line assembly, and there's a QA check downstream to keep them up to scratch, there isn't much difference there.
