obviously not. But anecdotally what I see where I live is that it is a large enough inconvenience that it makes an impact. If you work 8 hours, then have to spend 2-3 hours getting groceries you already have a 10-11 hour day not counting any other commuting you need to do. What if you have kids you need to get off a bus from school?
trying to blanket say anyone not willing to make that trip just isn't trying isn't fair.
It is well documented that low-income areas have less access to good education, healthcare, and other facilities. blaming the residents doesn't help them improve their quality of life. Not everyone will make it out of that.
