What If... We gave everyone free money with UBI? | What If

What is Universal Basic Income (UBI) and how could it help us deal with the coronavirus outbreak? What if... we gave people free money? The idea of a basic income is that everybody would receive a modest amount paid each week or each month without conditions, paid equally to every man and every woman with a smaller amount to pay for every child. Advocates for Universal Basic such as Guy Standing, co-founder of the Basic Income Earth Network, argue that it would be the ideal response to the crisis, but that it would also bring huge long term benefits, which he explains in this video. This video was produced as part of Digital Society, a publishing partnership between WIRED and Vontobel where all content is editorially independent.
