Society is in no way set up to support UBI. Everyone gets $1000 and then rent, food, and everything else become more expensive.
Instead focus should be on guaranteeing necessities like healthcare with Medicare For All, relinquishing student loan debt, and making public college free to attend. Bernie is the only one focused on universal coverage for all of these things.
Yang supports Universal Healthcare as a key attachment to UBI. [1]
He does care about the student loan problem, but has a less aggressive and more nuanced plan than blanket forgiveness. [2]
Traditional college is not a necessity for most people. We should be pushing for more trade school participation like most of Europe does and train people for skilled labor that won't be automated any time soon. [3]
Most importantly, Bernie doesn't seem to even want to acknowledge the coming wave of automation. And somehow, he thinks that a $15 minimum wage won't just accelerate the drive to automate jobs. Higher wages also does nothing to help stay at home parents or caretakers (mostly women) who find themselves completely dependent on their breadwinner.
And the person who killed five police officers and injured 11 more people in Dallas was a fan of BLM. And John Hinckley Jr. thought he would impress Jodie Foster.
The views of madmen don't reflect on the celebrities or groups they're fans of.
