Whatever an average person may know about the way his body works, there always will be some scientist who knows more and he will sell this knowledge to those who wish to rule over others.

Eh? Selling knowledge? Scientists aren't wizards, it's not like we have arcane knowledge, and sell our services to the highest bidder. They're also not working for commission. They earn salaries, and do whatever research they can within the limits of their funding. All it takes to be a scientist is to understand how and why things work. If anyone has this sense, they are a scientist. Maybe not in a professional sense. Kids are the best scientists. They observe with this amazing grasp for curiousity that has been beaten out of us through age.

Wikipedia exists for a reason. The only reason why some people see it as unreliable is because it is free for anyone to modify. However, for well-established topics, the knowledge is quite sufficient.

Knowledge used to be for the rich aristocrats who could afford such things. In this day and age, being an autodidact is even more possible than it was for Leonardo, also an autodidact. All it takes is an internet connection.

Whatever an average person may know about the economy there always will be some economist who knows more and he will sell this knowledge to those who wish to rule over others.

Whatever an average person may know about politics there always will be some politician who knows more and he will sell this knowledge to those who wish to rule over others.

Whatever an average person may know about computers there always will be some software engineer who knows more and he will sell this knowledge to those who wish to rule over others.

You can apply any profession to your quote. It's called capitalism. The art of selling whatever you are proficient at, be it manufacturing goods or performing a service. The only thing that isn't completely true is the ruling over others. The only truth in what you say is that corporate big wigs have power, if that is what you mean. The age of kings and queens is gone. It's now the merchants who control the world. And fortunately, they aren't screwing us over as much as they could.

I don't know about you, but I have a thirst for knowledge and wisdom. And I plan on sharing it with anyone who cares. Not for money or profit, but because that's the purpose I've given my life. I want to make this world a better place, through education and communication. Countless people I've met are the same. Not everyone cares about money.
