Musk has risked almost every penny he has on multiple occasions. He has created, commercialized or drastically improved four things (five if you count the boring company). The 1T of his wealth benefits society in the products we all consume, the environmental gains (he was the first to mass produce electric cars profitably), the jobs he has created and the taxes paid by him, his companies and his workers. Do you see any socialists doing any of these things? This is one capitalistic person. He's done more for the environment than any green party. He's created more wealth and better jobs than all communists combined.
Oh but one person shouldn't have that much power. We need socialists to own the capital and make decisions. Think about how incompetent your local government is at doing, well everything. My city takes 12 years to open a dog park in an open field, $16000 to put in a speed bump, $80 per injection at their safe injection site and $40,000 per bike in their ride share program. I'm sure that's about average for any socialists.
