A search for “statistically significant” yielded no results. So why am I not to assume, especially given the source, that this is more of that “Americans are lazier and less productive” thing that plays out daily in right-leaning media?
It's unwise to think of business owners as left or right leaning, or to think their espoused politics are any indication of how they will act when push comes to shove. Owners are always perpetuating class war against workers.
I disagree: tech leaders may be left-leaning on social issues, but they are not left-leaning fiscally. Corporate America as a whole - tech and media included (Fox, NYT, CNN, NBC) are center-right on fiscal issues. Tech companies may dress up their logos in Pride colors at the right times since that's free and earns goodwill.
