(Associated Press) Democratic presidential candidate Andrew Yang wants to give cash to every American each month. Susie Garza has never heard of Yang. But since February shes been getting $500 a month from a nonprofit in Stockton California as part of an experiment that offers something unusual in presidential politics: a trial run of a campaign promise highlighting the benefits and challenges in real time. Garza can spend the money however she wants. She uses $150 of it to pay for her cellphone and another $100 or so to pay off her dogs veterinarian bills. She spends the rest on her two grandsons now that she can afford to buy them birthday presents online and let them get the big bag of chips at the 7-Eleven. Ive never been able to do that. I thought it was just the coolest thing" said Garza who is unemployed and previously was addicted to drugs though she said she has been sober for 18 years following a stint in prison. I like it because I feel more independent like Im in charge. I really have something thats my own." Garza is part of an experiment testing the impact of universal basic income" an old idea getting new life thanks to the 2020 presidential race although Stocktons project is an independent one and has no connection to any presidential race.
