Take for a random example Steve Jobs. At one point he had some ideas, and those ideas made him some money. From that point, his money paid other people who came up with the ideas. Those people come with ideas, and many contribute a number of hours of their lives equal to what Steve Jobs does to the work, and yet Apple paid Steve Jobs an amount disproportionate to what those other idea generators received.
Were they riding Steve Jobs success?
The look for a better job, rinse, repeat idea is flawed. Imagine if 100% of people followed the get a job, get experience, look for a better job, rinse, repeat method. Regardless of their efforts, there are only so many high paying jobs. Only so many of those people will obtain the money of a CEO, despite everyone else working as hard. Only so many people can open a small business and make their own way. (Example, how many bakeries can be opened before there isn't enough money to be made running a bakery.)
It isn't about handouts. It's that only so many people can obtain large amounts of money, and that money makes them an exorbitant amount of additional money without the need for real effort.
