Fund a Basic income at zero cost, through the Fed. Indexation eliminates any potential inflation tax.
Businesses can decrease wages as much as they like, automate, outsource, etc. without worrying about harming the General Welfare. Why would unexpected, runaway inflation occur?
But as a hedge against potential price-gouging, index everything (incomes, savings, everything) to inflation so that purchasing power does not decrease.
Hold lots of challenges to stimulate individuals (on a basic income, or not) to innovate. Business can further reduce costs by crowdsourcing innovation. Again, why would inflation occur? Simply create the $6 trillion or so per year for a basic income.
