Last night Channel 4 in the UK aired a profile of Elon Musk. I admit I knew next to nothing about him so I was surprised to find out he was born in South Africa, but not surprised to discover he doesn't do failure, and takes a dim view of anyone who criticises his companies, especially if they work in them. What struck me most about him, is not so much his enthusiasm for space travel and the plain stupid idea that humans can populate Mars, but that I wonder if he has chosen a project that is not that difficult to achieve.
Think about it, once you have the machines and the fuel to get humans to Mars and back, all you need is a safe network of domes within which humans can live without having to wear specially designed suits. Setting aside accidents which I am sure will happen, and unforeseen environmental impacts on such a planet, as per The Martian, the project is not that hard to achieve.
Now compare the Mars missions with something closer to home: Homelessness. I wonder, does Musk not address a problem he can see every day if he lives in LA or San Francisco, because it appears to be a problem without a solution that does not bear with it the accolades that one assumes will accompany a 'manned' mission to Mars?
It has been calculated that the cost of ending homelessness in the US is $20 billion, so why don't America's billionaires agree to chip in a billion of their own money to end it? The stats are there, the justification is there, the pay-off would not just be the end of the visible signs of failure , but become part of a success story in which people without a home have a home in which they can live with dignity and one hopes, turn their lives around from whatever it is that has left them on the streets.
Maybe Musk should be more concerned with Main St than Mars. Or maybe he doesn't care.

"According to the Department of Housing and Urban Development, it would cost $20 billion to end homelessness in the United States. That is a big number, yes, but let’s put it into perspective:
