The U.S. economy is estimated to grow at between 2.5 to 3 percent this year, and it’s positively affecting the gig economy and its nearly 54 million freelancers who are telecommuting from home and co-working spaces across the country. The impact is huge because by 2020, at least 40 percent of American laborers will be gig workers, according to a 2010 study by Intuit.
