Final answer:
Desai's Slum Adoption Programme is not directly mentioned; however, Desmond's advocacy for a universal housing voucher program suggests it would be cost-efficient in the long run and is aimed at reducing poverty through stable housing.
Step-by-step explanation:
According to Desai, the Slum Adoption Programme is not explicitly described in the provided texts. The information given focuses on Matthew Desmond's arguments regarding housing instability and poverty, particularly the potential solution of a universal housing voucher program. This program aims to provide housing assistance to ensure people have stable living conditions. Desmond suggests that the program could lift millions out of poverty especially if combined with rent regulation.
Therefore regarding the question of why a city might prefer this program to hiring municipal workers it aligns with the broader goal of reducing poverty and maintaining housing stability, potentially leading to more sustainable outcomes than simply increasing municipal employment. The city might find the voucher program combined with rent stabilization more cost efficient in the long run, even if it requires more investment initially as it can encourage work incentives and contribute to tackling the structural issues of poverty.
