SGT Newman, Actually Texas could be considered self-sustaining, before the POTUS's last presidential run, Texas was the only state out of 50 that was operating in the black, that was the reason for the big push for secession from the country as every other state was in debt because of what the administration and Congress have created for the country, Texas was the only state not stressing over the national debt as they were capable of surviving if an civil war against DC were to occur, they have enough assets to close off the state and be self-sufficient.
