I think you are mixing two unrelated issues. Giving away your inheritance to other people's children won't suddenly make you surrounded by love. You will still die alone and unhappy. Better to just spend that wealth on hookers and drugs, or a sexy nun, or whatever makes you happy. I did not look at stats, but I think suicides are more skewed towards poor.

How is redirecting wealth taxes solves demographics crisis? Affluent people choose to not have children because there won't be jobs and happy life for them. Bringing more children to be hungry in ever more competitive world is evil. Poor do selfishly procreate as a pension plan. Skinning wealthy to feed poor always ends in gulag, because rich are rich because they are smarter. They will always escape socialist redistribution. That's how bitcoin is relevant in this discussion.

Demographic collapse is not the cause of the world's economic woes. Not a problem that can be solved. It is the effect of technological progress, of our success as human civilization. Machines are invariably getting better and cheaper than meat workers. Shrinking human population goes hand in hand with shrinking profit margins, whether we like it or not. Darwinian evolution.

In Japan, Korea and other Buddhist countries taking own life is not a sin. I share belief that the whole universe is one evolving entity, with individual plants/animals/people but cells in that organism. We will die off and get replaced by more efficient (inorganic) cells to get the evolution going. In your small econ box you will probably call all this delusional shit, or off topic, but that's ok.
