European nations have been taken over by socialist governments, which have sold most of their African colonies to the U.S.; and Canada, Mexico, and the countries of South America have requested annexation. Race conflict is a thing of the past, since the ‘dark elements’ of the American hegemony have died out.John Jacob ‘Jack’ Astor IV (1864–1912), often dubbed ‘Jack Ass’ in the press, was an American businessman, real estate builder, investor, inventor, writer, lieutenant colonel in the Spanish–American War, and a prominent member of the Astor family.

Astor was among the 1, 514 people on board who did not survive. He was the richest passenger aboard the Titanic, and was thought to be among the richest people in the world at that time, with a net worth of $85, 000, 000 when he died.Among Astor’s accomplishments was A Journey in Other Worlds, an 1894 science fiction novel about life in the year 2000 on the planets Saturn and Jupiter. He also patented several inventions, including a bicycle brake in 1898, a ‘vibratory disintegrator’ used to produce gas from peat moss, and a pneumatic road-improver, and helped develop a turbine engine.
