BlackRock works, but I was going to say China. Create virus. Destroy world economy. Buy up everything for peanuts.
China is currently mid-crash in its own real-estate crisis. One company, Evergrande, collapsed with $300B in debt. That is half of what Lehmen lost ($613B). 34 of their 50 largest developers that issue bonds are in default. Chinese development bonds have lost 87% of their value in the last 24 months. China will NOT be passing the US Economy any time soon. The surge everyone saw over the last few decades was going from undeveloped to developed. It is not repeatable. China is broke from trying to bail out their own economy.
