They don't seem to care about themselves either. It's their own land/water/air they pollute by letting corporations exploit them. It's their own people who freeze to death when their shitty power grid can't keep up with extreme weather, or who die from overheating while at work. It's their own family members who die in fertilizer plant explosions. Their own kids who are being mangled at trampoline parks. They're the ones living in the state with the highest population without heath insurance in the country.
Companies have convinced Texas that regulations are from the devil so that they can make money hand over fist at the expense of Texans and the people of Texas fell for it. They figured out a lot time ago that if you can convince a Texan that you're giving him freedom from The Man, you can bend that Texan right over and have him thank you for sticking it wherever it pleases you.
