If you expect an American politician to talk about getting rid of jobs, you will be very disappointed. I agree with your point, but Bernie Sanders is running on a platform of ideas that are overall quite popular and is still considered to be fanatically leftist. Talking about eradicating the need to work/have a job is political suicide in the US. This country prides itself on working hard and being employed. It will take a while to convince a meaningful chunk of Americans to reconsider what is undoubtedly a pillar of our cultural values.
That said, he did get asked about basic income in a reddit AMA and said that it could eventually be feasible, or something along those lines. That's as close as any candidate will come to touching on the topic of automation eroding our workforce.
He's considered a basic income program as the last resort of all resorts. It's a terrible position to take, but Hillary's answer was literally "lolmoms." I'm not even kidding.
People who may be affiliated with Sanders, assuming he gets in, will move forward with this. Robert Reich has outright said a basic income program
must happen, though I don't agree with his model. Milton Friedman's model sounds best, and that's a Republican model via Negative Income Tax. Better than taxing patents, which was Reich's idea.
Tim Canova, a man running to replace DNC lazy queen DWS herself is one who supports Sanders and thinks a basic income is a necessity. The fact someone who's studied law and public finance feels this is needed, and actually wants to represent the DNC, is remarkable. It's a shame the Democratic party isn't talking about the severity of our problems here, though Obama essentially spoke about the ultimatums we face from his State of the Union address.
I think the next generation of politicians will get it, but all of those folks are under the age of 40. We're run by people who are close to being senior citizens.
