30-Hour Work Week: A 6-hour day with no cut in pay for the bottom 80% of the pay scale.
Social Dividends: A "second paycheck" for workers enabling them to receive 40 hours pay for 30 hours work. Paid by the government out of progressive taxes so that social productivity gains are shared equitably.
In fairness, the 10 hours is not paid by the employer.. but by the richer people in the country.. I don't think this would work very well IMO:
avg wage (more than $16/hr.. we'll just say $16 to make it easy) * 25% bonus * 140 million currently employed people = 1.120 trillion dollars
Current government revenues (currently.. who knows what it will be after they destroy the economy): $2.119 trillion
So it would cost 50% of the current budget.
