Politician: Homelessness is a serious social problem, but further government spending to provide low-income housing is not the cure for homelessness.
Conclusion
Further government spending to provide low-income housing is not the cure for homelessness.
Evidence
The real-estate section of any major newspaper shows there is no lack of housing units available to rent. So the claim that people are homeless because of a lack of available housing is wrong.
Intermediate Conclusion
The claim that people are homeless due to lack of available housing is wrong.
Evaluate
The opening line — "Homelessness is a serious social problem" — is a concession the politician makes before pivoting to the actual argument. The argument is about whether more low-income housing spending is the right cure, not about whether homelessness is a problem. So the seriousness of homelessness is irrelevant to the conclusion: someone could agree homelessness is serious and still accept the politician's conclusion (or reject it). The line plays a rhetorical/concessive role, not a logical one.
Goal
Find an answer that captures the line's status as a non-load-bearing concession — something compatible with the conclusion either way.
