💸 Taxpayer Alert: 183% Over Budget
The F-35 Lightning II program has exceeded its original budget by 183%. At $1.7T, this represents billions in cost growth that could have funded schools, healthcare, or infrastructure. This is a pattern across Pentagon weapons programs — the military-industrial complex has little incentive to control costs.
