No probably not because Jews. I deliver to a dairy plant where most of the workers are aged 20-40. I just watched the shift change and every single employee walked in with a bag of fast food and fountain soda. This is a Union plant and the work ain’t that physical. This country will poison itself to death long before Chinks or anybody else needs to do the job.
All you need for walkability is to have all daily amenities within walking distance of your home. If homes, even detached, are clustered around a small local grocer (as opposed to a supermarket), school/park, barber, laundromat etc. then people can walk.
I honestly don't mind living in an apartment building so long as there's green space nearby and private storage for bikes, sports equipment, etc. But city planners don't give a shit about livability because they all live in gated communities, not apartments.
