What really is the contribution stocks have conceptually

Ok on this whole Elon Musk, one thing I want to add is right now he already has it planned out already, manipulating the market in his favor. This where he can benefit and subsequently control the market because of his popularity, plus his ridiculous wealth by simply selling shares of his stocks he bought in when the growth curve was high, giving a false sense continual growth to only cash out, then putting into it back into his stocks to again give that false sense of growth and opportunity that could be missed, just to sell again when he feels its reached its peak. This is exactly how the rich stay in power and manipulate the system.
