Re: Customers are vital part of the getting rich process.
It's not forgotten. It's called the 'tragedy of the commons' - once there are enough people in the system, they work to rip each other off (rely on other higher earners to buy the cars) rather than supporting it themselves.
Corporates, being the sum of their boards rather than individuals, kept away from this for a while. But they learnt to employ their requirement to provide shareholder value as an excuse for no-holds-barred greed, so they went the way of the rest.
