It is an issue. Not as bad as places like NYC, DC, or Boston, but still.
Its what happens when services are provided to them. They show up. They can be made to go away by starving them out, closing shelters, and letting the cops beat the shit out of them until they limp out of town for greener pastures. A lot of people seem to like that answer.
Mostly people just don't like to have to see them, be reminded they exist, that poverty happens. They call it a "quality of life" problem, that they have to see and be aware. Where its a real problem IMO is when you've got guys piled up around your business, detracting customers, blocking entrances, littering, shitting in the gutter, etc etc. But panhandlers and such have been part of the fabric of urban life as long as there has been urbanity. Thousands of years and no meaningful solutions. At least none even remotely humane.
