"The Market" as economists define it is the middle point of a bell curve. Everything 'averages out', even though that average is made of killer fucking sharks at one end, and people losing everything at the other. Besides, the results always tell the truth, and economists have poor results, because they're functionally poor people.
Everyone is always selling, money managers / Long term investors are selling you on an idea (5 - 10% returns per year, every year), and when you buy into that idea, you essentially tell your subconscious not to bring you ideas about how to make 100%, 200%, 300%, etc. How many people here have crushed the market with the super hard two step process of buy BTC and Hodl.
The few wealthy people I know all have the same attitude towards money, it's not about 10% a year, it's about doubling the investment, minimum. I know for me last year I made 300% return on the US election, in 10 days, on 80k I borrowed, at a total funding cost of $1300. I do nothing for the next 12 months and I've beaten every fund in the market by huge orders of magnitude. And it wasn't by saving money, it was by borrowing money, by understanding that money is a game, and you need to play to win.
As for 'access to knowledge', everyone has access to the same pool of knowledge, but everyone knows different things, inspired application of knowledge at just the right time, that's the key.
Not to mention the real game isn't about simply reacting to knowledge, but by putting your own knowledge out there. Warren Buffet can literally turn what he says into money, because he has the results, he can say buy X, and millions of Gopher's go out and do it. He can change the behavior of the market with his will. He can literally change the knowledge when he shares his thoughts, that's the level to aim to play on.
