The Disney heiress and film director Abigail Disney said wealth inequality has made it impossible to achieve the American dream, like her great uncle Walt Disney did, in a June 24 interview on "CNN Tonight." Disney is among a group of 19 ultra-wealthy Americans who signed a letter on June 24 asking presidential candidates to support a wealth tax. The revenue generated by the wealth tax could be used to pay for environmental initiatives, fuel economic investment, and fund healthcare, according to the letter. The tax would also protect America's democracy by reducing inequality, it added.
