This is not true because the bourgeoisie are class conscious and that helps them fool the proletariat who are not class conscious
But the bourgeois are free and the proletariat are many. If hypothetically everyone became conscious of class war and their place in it there is only one winner.
What I don’t agree with is that the person is saying that if everyone was class conscious then revolution wouldn’t be necessary. The bourgeoisie are class conscious and they are not willing to give up their class position peacefully. Therefore, that point doesn’t hold.
How does one become rich? Off the labor of others. If people were all class conscious they could simply stop the exploitation and work together for each other, enjoying the fruits of their labor and leaving the bougies to fend for themselves.
