The title of the article is "Doomsday Preppers are Socially Selfish", to which I (and one of the commenters) would refer the author to the book "The Virtue of Selfishness" by Ayn Rand.
To which she states, AND I QUOTE, "I read it in high school, it was published during my freshman year (yep, I'm really that old). I didn't agree with her version of morality then - that altruism was bad for human survival - and I still don't."
This is an Emergency Management Manager that states that altruism is good for human survival. As proof I offer to you historical precedent (in no particular order):
Mao Ze-Dong (China, 1958-61 and 1966-69, Tibet 1949-50) 49-78,000,000
Adolf Hitler (Germany, 1939-1945) 12,000,000 (concentration camps and civilians deliberately killed in WWII plus 3 million Russian POWs left to die)
Leopold II of Belgium (Congo, 1886-1908) 8,000,000
Jozef Stalin (USSR, 1932-39) 6,000,000 (the gulags plus the purges plus Ukraine's famine)
Hideki Tojo (Japan, 1941-44) 5,000,000 (civilians in WWII)
Ismail Enver (Turkey, 1915-20) 1,200,000 Armenians (1915) + 350,000 Greek Pontians and 480,000
Anatolian Greeks (1916-22) + 500,000 Assyrians (1915-20)
Pol Pot (Cambodia, 1975-79) 1,700,000
Kim Il Sung (North Korea, 1948-94) 1.6 million (purges and concentration camps)
Menghistu (Ethiopia, 1975-78) 1,500,000
Yakubu Gowon (Biafra, 1967-1970) 1,000,000
Leonid Brezhnev (Afghanistan, 1979-1982) 900,000
Jean Kambanda (Rwanda, 1994) 800,000
Saddam Hussein (Iran 1980-1990 and Kurdistan 1987-88) 600,000
There are many more. These are the products of the "greater good" (altruism) mythos. It is a failure of humanity to allow these monstrosities to occur simply because an evil philosophy is chosen over morally good philosophy.
