Wikipedia gives 24% for both healthcare and social security for 2014.[1] Total military spending is more complicated but is estimated at 28-38% of the total budget (though no citation).[2] That gives somewhere between 0.98 and 1.33 trillion, so I guess I was off there, but it has been much higher at (estimated) 54% in recent years.<p>Per capita healthcare spending is similarly estimated at $8,713 for 2014 or $9,146 for 2013 depending on which of those estimates you go with.[3] Presumably that includes total healthcare spending, public and private, but the issue is how much potential savings are there to pay for a UBI (by switching to a more effective healthcare system), so I think the total is relevant still, not just medicare + medicaid.<p>Your 33% number for SS seems to come from the inclusion of spending on unemployment and labor. The military spending being larger than total discretionary probably comes from inclusion of veteran&#x27;s benefits and other programs included in with mandatory.<p>The exact numbers aside, I think the larger point still stands that the money is there - once you start looking at how much money is already being spent it&#x27;s not hard to imagine getting a few trillion together for a UBI. Political feasibility is another matter, I agree it probably won&#x27;t happen anytime soon for that reason, but saying it&#x27;s economically infeasible just seems... wrong.<p>[1] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;File:U.S._Federal_Spending_-_FY_2011.png" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;File:U.S._Federal_Spending_-_F...</a><p>[2] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Military_budget_of_the_United_States#Military_budget_and_total_US_federal_spending" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Military_budget_of_the_United_...</a><p>[3] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;List_of_countries_by_total_health_expenditure_per_capita" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;List_of_countries_by_total_hea...</a>
