I quickly searched for an estimate of the homeless population within LA city: ~36,000. At 1.2B that is over $33,000/person.
Honestly, I wonder at what point can we look at these results and ask ourselves is it better to just give people $33,000?
With the population of LA County at 4 million, that 1.2B comes in at $300 per person taxed. That's $300 out of the pocket of each resident given to the cause. (But, I'm sure that a good portion of that actually gets pocketed by some officials along the way.)
