The Great Recession caused a nearly 5% drop in inflation adjusted per capita GDP in less than two years.  Since then, it has grown almost 10%. Of course that means less than 5% real per capita GDP growth over the last decade, which includes the Great Recession (see https://tradingeconomics.com/united-states/gdp-per-capita-ppp). But that is a poor argument against saving money on health care by shifting from premiums, deductibles, and co-pays to taxes. I guess saving money would lead to job losses in health care billing and insurance related activities, which may not be so great in a stagnant economy, but the expectation would be more jobs in providing actual health care and more competitive industries in general, due to better health outcomes and fewer people stuck in jobs because of health care fears.
