It’s highly unlikely PC is a billionaire. Pippa Middleton merches all the time and she looked to Australian business to pay for her wedding. If PC was a billionaire he could have helped pay for her wedding (3mil is nothing to a billionaire), AND would not need taxpayers to pay for his grandchildren’s schooling, salaries, or helicopter rides. Most of the RF merches. They may have money but they are not billionaires. MM wouldn’t need freebies, or Kate for that matter.
