I have a friend who owns several modest rental units. Some years ago she decided out of kindness to rent to some Section 8 tenants. The tenants trashed two of her units and were nearly impossible to evict. The tenants caused many headaches and cost her a lot of money.
She learned her lesson: No good deed goes unpunished.
Yes. Strengthening landlords' rights is important. The difficulty you describe is not the natural way of the world. It is an artifact of bad policy, in this case a systematic favoring by limousine liberals of dysfunction behavior, which they tolerate and defend as long as it can be confined to other people's neighorhoods.
The large scale housing projects that are the capitals of Underclass America are artifacts of bad policy. The concentration of Section 8 housing is bad policy. The transportation and land development policies that subsidized suburban sprawl and left poor people isolated were bad policies. The modern underclass is the product of bad policy on a dozen fronts. These policies need to be uprooted, starting with welfare, policing, and schools, but smarter housing policy plays an important role as well.
You know, all those white privilege things that do themselves and pay for themselves? Not to mention the taxes? Those are another $350 per month.
