> microwaves
Many cheap motels do not in fact have microwaves. Buying one for $15 is great if you live in a place where people are selling working microwaves for that price and eveyrone else is not also poor and looking for a microwave.
> They took the time, why can't everyone else.
Not if you're working 3 jobs and barely have time to sleep while being a caregiver. Some people don't get to take time off to do things.
> There are no such thing as food deserts. I've seen the maps, and yes, there are areas that don't have large grocery stores.
Perhaps talk to someone who'se lived in one? There's quite a lot of arrogance to say "I've looked at the maps so your problem doesn't exist" from wherever you're based on earth.
There are solutions in many situations but the cycle is vicious and you're one bad step away from getting eating alive in many places. Poor nutrition -> health problems -> limited time -> getting laid off for underperformance (or plain cruelty). It isn't always a way out in life without a dollop of luck.
