Economic growth has been slow for the last decade.
To understand why, it helps to consider the factors that cause growth rates to change.
Economic growth comes from upticks in productivity AND increases in the total number of hours worked in the economy.
When more people work more productively, the economy grows.
Productivity increases when workers produce more than they did before. This occurs either because workers obtain higher levels of education or because companies invest in physical capital like tools, factories, and equipment that enable employees to increase their output.
Recently though, productivity has grown at only a quarter of its historical pace, largely due to reduced investment. Economic growth has lagged as a result.
And the percent of people working today is much lower than previously expected. Even after taking into account the Baby Boomers retiring, there are millions of able-bodied adults who are no longer participating in the workforce.
Getting back to our historical level of growth is possible, but it will require policies that encourage people to rejoin the workforce AND policies that spur more investment in education and the tools that help make workers more productive.
