Activists spray painted a superyacht owned by Walmart heiress Alice Walton for a second time in an ongoing demonstration against the wealth concentration of the Walton family. The activists spray painted the letters b and t (for Billionaire Thieves) along with a clenched fist. The activists launched the protest to highlight the Walmarts’s mistreatment of employees and the impact their wealth has on the economy. The Walton family is worth an estimated $154 billion, according to Forbes.
