[T]he Golden State has no peers among developed economies for expanding GDP, creating jobs, raising household income, manufacturing growth, investment in innovation, producing clean energy and unprecedented wealth through its stocks and bonds. All of which underlines Governor Gavin Newsom's announcement last month of the biggest state tax rebate in American history. 

By adding 1.3 million people to its non-farm payrolls since April last year -- equal to the entire workforce of Nevada -- California easily surpassed also-rans Texas and New York. At the same time, California household income increased $164 billion, almost as much as Texas, Florida and Pennsylvania combined, according to data compiled by Bloomberg. No wonder California's operating budget surplus, fueled by its surging economy and capital gains taxes, swelled to a record $75 billion.

If anything, Covid-19 accelerated California's record productivity. Quarterly revenue per employee of  the publicly-traded companies based in the state climbed to an all-time high of $1.5 million in May, 63% greater than its similar milestone a decade ago, according to data compiled by Bloomberg. The rest of the U.S. was nothing special, with productivity among those members of the Russell 3000 Index, which is made up of both large and small companies, little changed during the past 10 years.

While pundits have long insisted California policies are bad for business, reality belies them. In a sign of investor demand, the weight of California companies in the benchmark S&P 500 Index increased 3 percentage points since a year ago, the most among all states, according to data compiled by Bloomberg. Faith in California credit was similarly superlative, with the weight of corporate bonds sold by companies based in the state rising the most among all states, to 12.5 percentage points from 11.7 percentage points, according to the Bloomberg Barclays U.S. Corporate Bond Index. Translation: Investors had the greatest confidence in California companies during the pandemic.

The most trusted measure of economic strength says California is the world-beater among democracies. The state's gross domestic product increased 21% during the past five years, dwarfing No. 2 New York (14%) and No. 3 Texas (12%), according to data compiled by Bloomberg. The gains added $530 billion to the Golden State, 30% more than the increase for New York and Texas combined and equivalent to the entire economy of Sweden. Among the five largest economies, California outperforms the U.S., Japan and Germany with a growth rate exceeded only by China.
