Billionaire Elon Musk may now be building his own city in Texas. He tweeted that he wants people to follow him, and work at his spaceport. He even suggested South Padre Island, which is near his Spacex launchpad. Many young professionals are expected to take him up on his offer. Musk seems serious about his need for workers. He’s donating a combined $30 million to the area for schools and urban revitalization.
