Monopolies, oligopolies, like the automobile companies, can collude and price fix, but they can't get around the fact that the mass of wage laborers are only paid so much, and it is always less than enough to buy all the consumer commodities which they produce; because the capitalist exploits a portion of the value they produce at the stage of production and appropriation of production for sale.
This is a self-evident characteristic of the market which Marx's approach makes clear.
