Instead of having an hour commute to move a few miles, you could have a half hour commute to move 30 miles.
This made land ownership possible for this group of people. Low value land that was too far from work was now usable for those same jobs.
Whenever I see propositions of removing lanes from freeways, I think how that benefits only rich people and landlords. I can afford to live near my company because I'm well-off, but I know plenty of people making 40-60k/yr that have plots of land 30-60 minutes from their jobs. They would otherwise be renting apartments 1/3 of the size of their home.
