I'm not from Texas or California but it doesn't intuitively feel true to me that Texans are better at investing and saving for retirement.

According to the first relevant search result I can find https://www.cnbc.com/select/average-retirement-savings-by-st... the retirement savings per dollar of median annual income in California is $1.44 and in Texas is $1.17

Do you think that's wrong? Or do you think it's a misleading statistic and doesn't contradict your belief?

It all depends on how those things are calculated. Are you including home value in retirement savings or not?
