Eh, the problem is self-correcting. The more firms act collusively and cooperatively against the interests of consumers, the greater the potential returns for an entrepreneur willing to defect from that consensus and her backers. Then there's a massive wealth transfer from the collective shareholders of the old cartel into the new business.

...you could argue that there's evidence this is happening now. The economy seems to have bifurcated into large mutual fund ownership of public companies, and narrow private ownership of new startups that are aggressively disrupting those public companies. All that's needed are more arrogant assholes who believe they can up-end whole industries.
