You're asking why businesses aren't employing people working across timezones AND deploying a second payroll system AND ignoring the cultural/benefits package incl. gov based subsidies the business misses out on due to hiring internationally AND the tax complications... Have you ever started a business and run it with a team of folk from across the world on a budget (not including just contracting people via UpWork etc)?
