Haves, have-nots, and modern economics

In modern economies, the ‘have-nots’ spend their lives in aspiring to be ‘haves’ and end up only observing and celebrating the affluent and effluent lifestyles of ‘haves’. This economy does not allow proportion of ‘haves’ and ‘have-nots’ to deviate from 1: 99. The simple maths it fails to understand is population keeps growing and with that, exponentially, the number of ‘have-nots’. How long would these economies survive against the pressure of billions who are forced with degraded ‘quality of life’ in the search of a mirage called ‘standard of living’…? I suppose what we are witnessing is a birth of that revolt against the modern economies worldover.
