Agreed. This simulator seems to make a lot of near worst case assumptions and paint with a very broad brush.
For starters:
Lifting 20lb is not going to take a toll on your body unless your body is already beat to crap from something else.
Most people can replace a window. If you don't then you probably know someone who can. Poor people trade semi-skilled labor around as favors all the time.
You don't need to join a gym to stay in shape, especially if your job involves manual labor. You also don't need to stay in tip top physical shape, just don't let yourself get seriously out of shape.
Nobody is doing credit checks for lower end jobs or lower end housing. They care more about your criminal record or lack thereof. If your poor you're either not going to use credit or your credit will be crap. Good credit isn't going to help you dig a ditch or unload a truck so you'll get hired anyway.
The whole point of choosing housing on the rural end of the available options is to reduce the cost of living and not have someone siphon the gas out of your car. In the simulation the shopping selector reflects city prices and the crime happens anyway.
Doing laundry in a sink, tub or 5gal bucket is a perfectly fine option if your washer doesn't work. It also doesn't cost $30 to go to the laundromat. You don't just wear dirty clothes. That's what college kids who've never lived on their own and lose their laundry card do.
I get that the whole point of this game it to make a statement but it paints a picture that seriously undersells the resourcefulness of poor people. It's also very clear that the decision tree in this simulator was written using a set of assumptions about how certain problems be solved and those assumptions were either made in an ivory tower or were designed to mostly go unnoticed to those in ivory towers.
edit: Yes I have had jobs like this. I know exactly what they're like. I've been a janitor, I've worked in food-service, I've done under the table construction, I've worked for a temp agency. I've literally dug ditches and scrubbed toilets (not that bad on average, watch out for the edge cases though). If you expect me to have a lot of sympathy with people who lift 20lb in a 70deg warehouse then you will be disappointed. Yes it's a crappy job that pays poorly and I'm sure it's soul crushing but it's not the pyramid building slave labor that some people like to equate it to. The lack of advancement opportunities (advancement to better paying jobs) in some of these jobs are what I consider the primary reason that people in these jobs can't get out of poverty.
