One major flaw of sincere democrats (many aren't sincere) is that they often are perfectionist who take an "all or nothing" attitude. The problem is that with all or nothing, you usually end up with nothing. So rather than allowing children to have "imperfect" parents (perfect ones are rich have houses in the exact configuration that is considered proper), then children get no parents.
Same with housing. Democrats would rather you be homeless than live in "inadequate" housing.
