Have we? California's marginal tax rate is over 50%, higher than many European countries. The Internet suggests that someone making $260,000 (200,000 pounds) will pay about 41.5% of their income in taxes in the U.K. https://www.thesalarycalculator.co.uk/salary.php. Using a similar tax calculator for California suggests that they'd pay about 39%. I assume the U.K. is also in a post-Reagan, post-tax world?
Must be Reagan. Couldn't be total mismanagement at all levels of California government.
