Where to begin? Let's start with budget. Some 31% of the Texas state budget comes from the federal government. That goes away. The article talks about keeping social security for those receiving it, but not making them pay any kind of income taxes - including that flat tax they talk about. Around 2.96 million Texans receive some sort of Social Security payment - old age, disability, survivors, whatever. That's over 12% of your population and congratulations, you just picked up that tab. On the plus side, you won't have to help fund any other state's social security, but your flat tax, levied on whoever is left, will have to fund it all. Then there's the national debt. Texas has 7.8% of the total U.S. population so 7.8% of the $12 trillion debt is $936 billion you now owe. Texas total debt just went up by a factor of 45. You will now have a defense budget you have to fund. You'll get some military equipment from the U.S. - 7.8% of the total. You'll have to buy the rest as well as pay for the troops to man them. You will have to establish and fund diplomatic service, your own air traffic control, your own border patrol, your own infrastructure through your own taxes.
Getting the picture? Whoever said freedom isn't free knew what they were talking about.
Your assumptions are way off base...who says we would have to take a portion of the US debt with us...think again..that’s why we would leave! You show little understanding of a real world scenario and even less of us Texan’s grit and determination.
