A new Harris Poll finds that a whopping 85% of blue-collar workers say that their lives are headed “in the right direction.” The high optimism level may have much to do with the booming economy. The latest economic numbers indicate that the surging economy shows no signs of slowing down. On Wednesday, the Commerce Department raised its estimate for second-quarter GDP growth to 4.2%, which means that annual growth for the first half of the year now is above 3%. And with all indications pointing up, it has become increasingly likely that growth for the entire year will be at 3% or better. The country hasn’t seen a year like that since 2005.

On top of the good GDP numbers is news on median household income, which is now up more than 4%. As Investor’s Business Daily reports, “Inflation-adjusted median household incomes in July hit $62,450 according to the latest release from Sentier Research. That’s the highest level since Sentier started tracking this more than 18 years ago. And if you combine Sentier’s numbers with annual Census data, median household income is at all-time highs.”

IBD continues, “More interesting is the fact that median household income has shot up more than 4% in the 19 months since Trump took office. It had been flat over the previous year and a half. Over the course of President Obama’s entire eight years in office, median household income climbed a mere 0.3%, Sentier data show.” Is it any wonder optimism is so high?

Harris also noted that 51% of blue-collar workers believe that the country as a whole is headed in the right direction, and 80% said that they are “very optimistic” about the future. 88% believed that their children would likely attain a better future than they. Needless to say, the large swaths of the country that Hillary Clinton and Democrats maligned and ignored — and then lost in 2016 — are clearly reaping the benefits of their vote. Go ahead and try convincing them that they voted for the wrong candidate.
