Well, we do already fund a ton of foreign aid all over the world, so quite a lot of that is already happening. But to address those particular things: homelessness is not a problem where simply throwing money at it magically solves it; it’s incredibly complex. New York City alone spends 3.5 billion dollars a year just on homelessness. The only financial solution to gun violence is to bribe the SCOTUS to repeal DC v. Heller. Drug policy is largely in the hands of the states, but even then, there’s no simple solution to it, particularly when you have to deal with local politics for things like treatment facilities. Prisons are largely state operated. Personal debt is largely outside the scope of the federal government, but even then, student loan forgiveness was attempted. But to throw a number at it, redirecting all Ukraine aid towards individual credit card debt would pay for only 10% of it.

Are there particular federal programs of comparable financial impact with sufficient political support that you think would pay significant returns if boosted by foreign aid money (ignoring the general decline in global stability that would ensue).

Will you be willing to pay higher taxes to fight off the drug cartels in Central and South America?

I mean, the economic dividends there are obvious. If it really was as simple as throwing some money at Central and South America in order to make the cartels vanish forever and turn those countries into stable countries that we could do significant trade with, we’d earn far more than we paid. But that price tag doesn’t actually exist, because these problems are more complicated than simply throwing money at them.
