Still frustrating that people will somehow defend the minimum-wage/rent disparity.
It'd be interesting to find out if two people could afford a studio or 1-br for 4 jobs or fewer. (I'm guessing not, but you never know.)
Though you're right that a 1-br + living space should be "decent" for 2 people (the 2-br probably has a living +kitchen too, so is probably not bad in living arangements). Studios are usually a pretty tight fit (euphemism) for 2 people I'd think though.
It enforces a minimalist aesthetic, excellent cooperation, solid space management and living a good chunk of your life out of the house. Which makes for a nice lifestyle.
However your mileage may vary (and I think it certainly matters that we chose to live this way, and where not forced to...)
