Tax companies a % of what they save by reducing head count. Salary, benefits, insurance, everything. They still save $, but not as much - they pay into a fund for UBI. And eliminate loan interest tax deductions for loans (totalling) over $X (some reasonable threshold that doesn't penalize middle class mortgage holders).
And to the poster above, UBI is for everyone, so those still working get UBI plus a paycheck - that's how it's fair.
We are NOT economically prepared for the renaissance coming. And our octogenarian leaders don't even understand how to set up a printer. Something's gotta give or the economy will collapse. Some estimates are up to 25% of jobs in the next 10 years.
