I would argue that the capitalist class shouldn't exist. Beyond the horrible human consequences of alienation, exploitation, etc., they are a superfluous class. Society needs workers, it will always need workers, it would function just fine, much better, in fact, without capitalists.
Capitalists will always rule, nomatter who governs, because they own the means of production, therefore they control it. The state primarily functions to enforce the hegemony of the capitalist class, and serve it's needs. The bourgeoisie are fractious, and divided and the state works to effect a consensus between them that they are incapable of reaching.
I fully applaud any effort to fight for the working class, but so long as capital rules, exploitation, alienation, and all the myriad evils that go along with it will endure.
Well you have certainly put forward some valid points on the evils of capitalism. If this there is no doubt. However, I think this analysis has some shortcomings.
First of although you have correctly identified the source of capitalist power as being control of production, I don't think you have penetrated deeply enough to the root of the problem. Currently capitalist control of the means of production is problematic because people in general have been led to believe that consumption of commodities is the source of happiness, freedom and empowerment. Because of this fundamental false belief, capitalists have been able to punch above their weight so to speak. They control the means of production of these items, so they essentially can control anyone who lives their life on this basis. Therefore they have a disproportionate amount of control over the political system and the system that is used to create the propaganda that controls public opinion.
Although it is true that a type of happiness comes from the consumption of commodities, it is a temporary type of satisfaction that is like that experienced in a dream. When the dream is over the happiness vanishes and one is again confronted with the harsh reality that in order to obtain these commodities, he must work very hard in the service of the capitalist.
There are different types of power. The power to influence opinion is very crucial. This power has been usurped by the capitalists who have been able to influence intelligent people to create propaganda that serves the interests of the capitalists. People need to be trained to understand that a more substantial type of happiness comes from the cultivation of knowledge. Furthermore, they should be taught that they should respect persons who have demonstrated practically that they are seriously engaged in the cultivation of knowledge. A thoughtful person, who is observed to be clean, truthful, self controlled, merciful, tolerant, and devoid of feelings of animosity towards others is certainly fixed in real knowledge, and these people should be held in the highest esteem. Public opinion needs to be shaped by these persons, and not by capitalists.
Another problem with your analysis is that you see the capitalist class as unnecessary and feel that they should be removed from control of the means of production. It is not possible to eradicate the capitalist class. That is just like trying to stop women from trying to look pretty. That's their nature, and some people will have that nature, no matter what you do. Even if you are able to stop them for some time, they will just re-emerge. So the eradication of the capitalist class is not practical. Not only that, but they perform a necessary function. Human society needs commodities, and capitalists play a crucial role in supplying those commodities. Again, the problem is that they currently have much more power than their actual value, and that is what needs to be corrected.
