Best? I don't notice anyone offering it as the best argument... Certainly nothing like the ONLY argument.
But it IS something else to think about.
In addition the money the government pays directly to the state, there's the salaries the service members and their dependents are spending to live in the state.
And there are other things of a similar nature. I'd expect 'out of state' tuition to go away, for example.
Nah, dismal has already told us Texas won't need to worry about that, because they won't need a military after the leave the US.
I seem to recall dismal's position was that military spending (including salaries) is a cost, not a benefit.
Perhaps dismal feels some amount of money the US spends on military could be more productively spent on other things, and some of those people drawing military salaries could be redeployed into producing more useful things.
