Regions with weaker non-compete enforcement have historically seen more employee-founded startups in the same industries, since a departing worker can build in the field they know. Supporters argue that restricting movement is therefore a drag on the formation of new firms, not just on individual wages. Critics respond that the comparison is confounded by everything else that differs between those regions, and that causation is hard to isolate from culture, capital access, and university presence. The correlation is consistent across studies even where the mechanism is contested.
