You need to invest in the initial services. If you decide to simply increase the number of affordable housing units, you bring the victim back to poverty. You don't help her get out of poverty.
When we provide our services, our purpose is not to place a victim in affordable housing for the rest of her life. The idea is that she will regain control, acquire the tools she needs to be financially independent and be able to afford other housing. The idea is not to leave her in affordable housing. It's a second or third step solution.
By investing in services provided upstream, we can better equip the victim and we won't need as much affordable housing.
