Elon has an incredibly low cost of capital, which produced real value for his companies. High valuation companies can acquire other companies through stock transactions and encounter relatively less dilution. They can integrate these companies vertically and create more value. Value begets value.
@bustitopen420 Correct. But someone can create a trillion dollars of value by building awesome businesses that offer products and services that everyone wants to buy.
@EdMarkey Elon creating amazing things and getting more wealthy doesn't take wealth away from others. You and your corrupt friends in Congress who spend like drunken sailors don't have a claim on anyone else's assets.
