Most of these perspectives come down to those that have managed/owned private businesses with their own capital at risk or have been in positions in public companies with financial accountability and those that have not.
As was said by others, it comes down to the skills you have, the value you provide to the company, and the going rate for that value/service in the marketplace. All of the emotion, name calling, and histrionics will not change that dynamic.
If you have a job that requires such minimal skills and experience that a teenager or a person off the street with a couple days of basic training can do, that is not a valuable skill in the marketplace and your role (by its very definition) can be quickly replaced. To expect that one can support a family, own a house, even live by themselves on an entry level job is just not realistic.
If you want better pay and an elevated standard of living, you must learn/develop new skills that employers value. It really is not more complicated than that, unfortunately it just comes across as "harsh" or "mean", but financial reality is not always pleasant.
If a person's job is waking up Jose in the Tiki Room every twenty minutes (and I did it so please don't tell me it is difficult job) or serving popcorn off an ODV cart and they think they are worth more in the marketplace, just simply apply at other theme parks - if you are being underpaid for your skill they will gladly pay you more to acquire you, if they won't increase your pay, then you are being fairly compensated for your skills in the marketplace. Simple.
