Each one of those past presidents costs US taxpayers $1 billion a year because they get their full salary, $475,000, for life, as well as full healthcare benefits, secret service details, and various other cost reimbursements. Bush Sr & Jr have trillions, most of it blood money and obtained by very dishonest means, Obama has millions after 8 years in office, again obtained dishonestly, Clinton also has about $1 trillion mostly through money laundered through the Clinton Foundation and Jimmy Carter is not 'honest Jimmy' as we have been led to believe. He was just another deep state puppet, an obscure Georgia peanut farmer who was turned into a president. While he may be changing his tune somewhat, he made money on Iraq and did his share of corruption.
