Most who are not Flat Earthers want to mitigate our planet's population overshoot in order to soften the coming collapse. However, the real value of a fortune is "how much labor can that fortune command?" And, like everything else, the greater the supply of laborers the cheaper their price.
Thus the rich have always wanted a large, poor population. In most nations the rich control the church, the media and politics. This explains why discussion of population reduction is taboo.
Yet there remains another way we can make a significant dent in population overshoot. About 9.5% of a developed nation's healthcare spending is used in the last year of life . About twice that (or 19%) is spent during the last three years of life. We can take healthcare spending as a proxy for "unhealthiness" or "unhappiness". Using this proxy we see that the last three years of life are commonly five times as unhappy as normal life. And the last year of life is over seven times as unhealthy/unhappy as normal.
The rich have no concern about population reduction among retirees. Thus there is no religious, media or political taboo against pushing the use of "EZ-Out Pills" to clear seats on spaceship Earth. EZ-Outs are heroin-based pills that provide an extreme two-hour high followed by a mortal overdose. While not the whole or even the best solution, the widespread use of EZ-Out pills by those diagnosed with a terminal illness will soften the human and planetary suffering associated with the population overshoot our world is now experiencing.
