Clearly the problem in all of this is that these markets are rigged. Imagine if the most knowledgeable investors were banned from trading stocks, or had artificially low bankrolls. It wouldn't be practical for individuals to invest in the market because everyone would assume they were getting ripped off, and the price was totally separated from the value of the business.
The fact that the most successful investors have the largest effect on the price is exactly what makes the market fair. A layman can login to manage their 401k, put in a market order, and know they are getting a fair price because many people, much more knowledgeable than the layman, are competing to set the price.
