The real elephant in the room is civilization: the system that feeds human ego and isolates the human animal from the resources that its offspring will need.
If humanity’s activities were centered on cooperative generosity to future natural resources rather than numbers of consumptionists, the population and most equality issues melt away with competitive fanaticisms.
We can start by putting the actual costs of purchases at the decision point: all civilization costs as sales tax-based UBI and healthcare (everyone would need basic tools to contribute their creative labors).
There are plenty of ways we can reverse our concepts of economics so that we stop viewing each other as competitors. Ironically, the design has mostly been worked out by the Right (FairTax.org) and the Left just needs to negotiate the rate.
