But moving them to the area 3 hours drive away from the city where there's actually space to build some of these things doesn't help them deal with joblessness (or needing a second job to pay down debt, when you lose 6 hours/day to your commute) since employment is generally easier to find in a city. In most of these cases, what's needed is not to expand low-density areas with marginally higher density, but to increase density in higher density areas so that housing there becomes affordable, or to offer temporary free/subsidized housing in those high-density areas until people are back on their feet.
