I like @Ron Whitfield's ideas on the homeless.  They mesh well with CB's tremendous story on the homeless settlement at Wai`anae a while back.   Many of our homeless neighbors are capable of helping themselves, if given a bit of help. 

I partially agree with @Jane Lee's complaint that we can't pay more taxes to care for the homeless.  I say partially, because it assumes the current regressive tax structure that places too much burden on the middle class and poor, and too little on the rich.  

However, if we recognize that wealth and incomes are skewed to the rich at historically high levels, then we might want to consider bringing back the progressive tax structure we had when the middle class was prosperous and homelessness wasn't an issue.   Instead of treating the symptoms of homelessness, progressive taxation would get at the root cause.
