so how are you going to handle the furious masses who don't want their elderly or unemployed relatives killed? i'm a hippie peacenik, but if you try to kill my retired relatives or unemployed friends, we're going to have a problem.
you are also completely wrong about "value." there are many different ways to contribute to society, and the elderly are vital. youth worship is a relatively recent phenomenon. cultures in the past almost uniformly revered their elders, and even today, this is the case for many of us. you think i have more wisdom than someone of my relative IQ who is twice my age? right. the twice as old version of me would pat me on the back and say, "oh, man, i remember that. check this out, though." you kill off the wise, and you'll have a society of fools.
I really agree that many elders have excellent wisdoms. I never proposed eliminating all of unemployed elders. There is such a sentence in my original text:
All of the old people unemployed
for a long time, such as two years, will have to accept euthanasia.
The wise elders are able to get a job within 2~3 years. The elders who are not able to do so are useless people without potential.
And you should think about No.3 part with No.2 together. In No.2 part, I said that all of marriages and families would disappear. When all of marriages and families disappear, you will have no relative. All of my ten parts are not realities but trends of future. I don't think they will become realities in a short time.
if competition is the goal, i'd rather see us strengthen anti-trust rules and break up too big to exist corporations. also, i don't really see a problem with being able to live off of your investments without working. i do, however, want to see more opportunities for those who have not inherited wealth to achieve it. that is the real problem; there are too many rungs missing from the ladder. confiscating all non-residential property is a ludicrous and unworkable proposition. it has been tried, and it failed.
smaller humans could replace the tigers and lions to dominate the earth because human were wiser. capitalists could replace the feudal aristocracy because capitalists were wiser. powers of wisdoms was the main driving force of human history.
so wisdoms are base of capitals of the capitalists. internet has made wisdoms flow and spread at unprecedented speeds all over the world. so all of property right will flow at unprecedented speeds between different people. too fast flow of property right will make most of people fed up with the changes of property right, which will bring nationalization of enterprises and lands.
"protective suits" won't stop violence. violence can only be stopped through general evolution of culture and specific genetic evolution of humanity. as much as we like to pretend we're not animals, we are still tribal primates competing against each other for access to resources. figuring out a cultural way to eliminate tribalism would be infinitely superior to "protective suits," but it still won't eliminate the fact that we are genetically programmed for anger, tribalism, and war.
nobody can stop birth of new lives and death of old lives. nobody can stop that some people become powerful and happier, and that some people become weaker and more painful. those are force of nature. so wars between people are inescapable and any evolution of culture is helpless.
so the best self-defense way is protective suits. if you may own guns, the protective suits must be bulletproof. the better your weapons are, the better the protective suits must be. in order to reduce the cost of protective suits, governments should strictly prohibit all of the people except policemen and armymen from owning the offensive weapons, such as guns, which could make our protective suits lose efficacy.
perhaps protective suits will not stop violence. but, facing the protective suits, tall or strong males will lose advantage of their bodies, which will increase the importance and powers of wisdoms.
