Whatever "solution" is proposed, it has to pass constitutional muster and there must be money to enforce it. Good reminder that the U of O area enacted an ordinance that does help and appears to not violate the Constitution. But I don't know if there are any details that have kept this being enacted elsewhere.
While I support efforts to deal with the problem as it arises in certain areas, I am more concerned at the continued stratification of wealth where the the wealthy increase their share of the total wealth while the middle and lower class lose more of theirs. When more people work for a pittance and have very little hope in life, some turn to drugs and become homeless. Or they are born into poverty. Not excusing their choices, but the very low income have a much harder time reaching the American Dream than nearly anyone who has money can appreciate.
