There's a similar visa in South Korea, the D-8 visa, which requires you to invest 50M Won (roughly 50,000 USD), either in some business or to open another business, and some people have gotten frustrated that some have just invested for the visa and never done anything further as the government doesn't track beyond the initial investment. In this, and in the US case, the government should track to make sure it's not being abused by people who just have a lot of money and want to live in the country.
