OK, you have a point: the homeless do get some benefit from City services. Though even that system is broken. I pass by several homeless people lying in the doorways every day.
It may be possible that there's a disconnect between "I'm offended by seeing street poverty on a daily basis" and "the system for dealing with poverty in SF is broken".
Unless your plan is to turn all homeless people in SF into Soylent Green, in which case you should run for mayor and good luck with that.
You propose to reduce property tax to 1%. Property tax is what pays for schools, it's not some kind of source of government waste as you seem to imply.
You probably don't know this, but this year, schools in SF were shut down for a extra week each year because of lack of funding. That's a week of schooling that my kids were supposed to have and they aren't getting because it's impossible to bring in the correct amount of money to keep our schools open. How would you propose to pay for schools if you slashed property taxes to 1%? (Hint: bake sales only take you so far.)
