California is bleeding, on average over the past 10 years, 60,000 people per year to Texas and that number is growing. California's total population continues to climb though (Texas is growing faster still though by about 2.5x). At the same time it appears Texas GDP per capita is growing twice as fast as California and will surpass California before the next census.

None of the data present, in either the article or the comments, align with Texas or California. Together those two are about 20.6% of the total US population. While there probably is a growing divergence exactly as the article claims it appears the described cause of that divergence is completely out of alignment with what the article claims.
