The military is overfunded by alot. I'm not saying there should be no military but even the military says they have too much funds. And I said military for the fact is one of the largest % of our budget.
Corporate welfare is another area to reduce expenses but it isn't close to what we could do to the military. (Wellfare is another large % but a lot of is not to companies. It more so welfare to poor people. Though the debate on whether those welfare are great is debatable)
Ideally we could do both and than just use all the money we cut from military and corporate to then put UBI. Now only would inflation not be higher and Gov not be in debt to entities. It be cheaper to run too.
