Hardly unique to America, tons of countries offer "Golden Visas" where committing enough resources to the country gets you an expedited or guaranteed Visa. The exact amount and details depend on the country, with richer countries obviously costing more, but tons of countries will straight up let you buy residency or citizenship. A few examples:
America - $900,000 investment for permanent residency (EB5)
Ireland - €1.0 million investment (plus €2.0 million net worth) for permanent residency for your family
Portugal - purchase and renovate at least €350,000 in property for residency, with an expedited path to citizenship
Germany - €360,000 investment for 3 year residency with a path to citizenship after 8 years
UK - £2 million investment for 3 year residency with a path to citizenship after 6 years.
