Washington state lawmakers have advanced a 9.9 percent income tax on households earning over $1 million to address state budget gaps.Former Starbucks CEO Howard Schultz announced his retirement and move to Florida following the legislation's approval.This migration of wealth aligns with a broader trend of billionaires purchasing luxury real estate in Miami as they seek to navigate shifting tax policies in high-tax states across the USA.Schultz maintains that his primary motivation for the move is proximity to his family while managing his assets through a new private office.
