You're unfortunately very correct. Housing aimed at the homeless (living on the street type homeless) increases crime and trash in the area. I sympathize with people who buy a house and then have a transitional housing project built near them because they bought their house without expecting that change. However, it has to go somewhere.

It's a problem here in Seattle that a lot of these homeless services get placed in districts which have a lot of minorities or are lower income in general. It's not fair--extremely classist--and these services should be spread out and include the wealthier, whiter neighborhoods as well.
