If you think it is a problem, whether or not we do, if you are serious about it you will have a solution. But you have not really presented any non-biased evidence that it is a problem. Further, two-parent households are better, but it does not follow that single parent households are a problem. Additionally, there have multiple posts suggesting solutions which would support single parent households. Your retort amounts to incentives, which suggests single parents want to be single parents out of some level of convivence. Where is the data that says single parents would prefer to single parent? Beyond all of this, is a single parent, mutigenerational home in a middle class neighborhood worse than a two parent household in a poor neighborhood? Are there any scenarios which would change your view? Beyond that, how do you think that punishing single parents helps kids? apples and oranges. And you don't understand cancer because there is not cure for cancer, and probably will never be a cure. Treatment is probably the word you are looking for, but even that is not comparable.
