Inequality won’t increase indeffinately. At best, it can vary, but it will settle at some value (which won’t be in the vicinity of 0, neither that of 100%). Quite simply, the wealthiest people around are those in the business of mass consumption. You can’t be a very large business unless you cater for the masses. So it’s absurd to say the masses will be “skinned” and left with a decreasing share of wealth, when these people are precisely the ones marketers must target to enter and remain in business. A business must please its customers to be viable.
