Not all corporations are evil, lol (I know you didn't claim that). Everyone wants cheap gas..
I started out many yrs ago working at a couple small/med sized companies, but most of my career was at large corporations (Fortune 75). They both have their place. Some products/services are nearly impossible for small companies to invest and produce ...and can require millions (even billions) of investment before a penny is earned. And it works the other way around too ...small companies can be very innovative and responsive ...quick to put out new products/services.
Kind of like designing/developing a new Ram pick-up model that contains 15,000+ parts an enormous amount of resources to pull together. Then constructing/testing prototypes, designing/building a new plant to building it in, staffing, salaries, etc. Selling and servicing problems.
I personally enjoyed working in both environments.
