The Job Guarantee and Inflation

I understand how it isn’t inflationary in the sense that he describes here, but what about the recourses required to put everyone to work, won’t the prices for these things go up? Also, won’t the private sector have to raise wages to compete with a guaranteed job, when no private sector job is guaranteed, thus increasing prices? I’m pretty new to economics, just trying to understand

"Full employment" and a job guarantee was a solution during the great depression. They're not realistic solutions today with automation/ AI/ technological unemployment.
