I just saw the news in BBC (of England) that Elon Musk who owns Tesla Cars is now the richest man in the world. It was his pioneering businesses that made him rich. Look at Paypal which started the money remittance center that now Paypal is the biggest. Add to that the pioneering space travel which is really interesting can make the moneyed people pay the exorbitant fare. With the electric car that can fight off the smoke emission problem of gasoline-fed vehicles.
