The MAO-A gene is also known as the 'Warrior Gene' because people with it tend to be more aggressive than people without it. Happiness and the lack of aggression would logically be correlated.

India is a country that receives billions of dollars per year from countries around the world to feed its people and yet the Indian government thinks they can find US$75 million to send a probe to Mars?!

Ah, but it does work! Ever heard of non-extradition countries? There are quite a few of them:

Afghanistan, Algeria, Andorra, Angola, Armenia, Bahrain, Bangladesh, Belarus, Bosnia and Herzegovina, Brunei, Burkina Faso, Burma, Burundi, Cambodia, Cameroon, Cape Verde, the Central African Republic, Chad, China, Comoros, Congo (Kinshasa), Congo (Brazzaville), Djibouti, Equatorial Guinea, Eritrea, Ethiopia, Gabon, Guinea, Guinea-Bissau, Indonesia, Ivory Coast, Kazakhstan, Kosovo, Kuwait, Laos, Lebanon, Libya, Macedonia, Madagascar, Maldives, Mali, Marshall Islands, Mauritania, Micronesia, Moldova, Mongolia, Montenegro, Morocco, Mozambique, Namibia, Nepal, Niger, Oman, Qatar, Russia, Rwanda, Samoa, São Tomé & Príncipe, Saudi Arabia, Senegal, Serbia, Slovenia, Somalia, Sudan, Syria, Togo, Tunisia, Uganda, Ukraine, United Arab Emirates, Uzbekistan, Vanuatu, Vatican, and Vietnam. Also note that Taiwan is one for now but the US is currently talking to them about it.

He fails to explain how many jobs will be created by new technology in the next 18 years. Technological Unemployment is one of the most powerful forces in market economics, but when those people become unemployed they become available in new areas using technology not yet created in the present time period. Take the Agricultural Revolution, it ended with mass unemployment due to the advent of John Deere's steel plough, but those unemployed masses moved into the cities and started the Industrial Revolution, a nett movement of 94% of the working population from 1800 until 1995 (Rifkin, The End Of Work, 1995). Note that this figure doesn't factor in the increasing participation of women in the work force.

Australia is full of animals and insects bred to kill anything else that they come across. Even the cute looking Koala is extremely vicious in the wild, their claws and teeth are razor sharp for climbing trees and eating leaves. Try New Zealand, there isn't much that can kill you, let alone bite you, as the European settlers, Maori and intentionally released European species of animals have killed off nearly everything remotely dangerous.

Those who have the ability to travel will do so if the place is better than where they are now. The world once only allowed in people who could get there by themselves, and had something to offer the host country. Now any man and his dog can immigrate and countries are struggling to find legal reasons to say no to them because of human rights legislation set up after WW2 by the United Nations. 95% of all refugees never get a job in their host country which results in a 100% drain on social services, infrastructure, utilities, etc. because even the 5% who do work use more tax money than they pay. This assertion was backed up by a recent British study that did the calculations. Supreme Justice Asher Grunis of the Israeli Supreme Court recently ruled that "Human rights do not prescribe national suicide," and with these few words may well see the western world turning against the flood of illegal immigrants, asylum seekers, and assorted refugees into First World countries from the Third World.

You will need Nazi Scientists to teach you how. Got any more you can kidnap? ;)

Then you simply have to make it profitable. The XPrize is a great idea for low cost small companies or individuals but for the larger companies it isn't worth the risk as the cost to produce the prototype is as expensive as the reward, which isn't even guaranteed. Of course it is the larger companies that are fat and bloated, so they can rarely produce a cheap solution. NASA could contract out for all the different parts needed to complete a project, with NASA bringing them all together like the U.S. Air Force does when it is building combat aircraft. This would mean limited NASA participation with the design and oversight aspect, and nearly all of the actual work going to private participation when it comes to the construction.

"You develop an instant global consciousness, a people orientation, an intense dissatisfaction with the state of the world, and a compulsion to do something about it. From out there on the moon, international politics look so petty. You want to grab a politician by the scruff of the neck and drag him a quarter of a million miles out and say, 'Look at that, you son of a bitch.'" - Edgar Mitchell, Apollo 14 astronaut
