I love Philadelphia, but I can also be angry that the streets smell like urine and most neighborhoods are cockroach infested wastelands where I feel the need to dash through after 1 or 2 AM and many other problems I would prefer not to have here. European colleagues visit and tell me it's embarrassing that the cities are in such disarray. I have no means of comparison, but I do think living conditions are clearly suboptimal.
I was there in late September during a heatwave. Smelled fine. Didn't see roaches, felt safe at night. 'I DON'T FEEL SAFE IN THE CITY' is such a weird Americanism and even worse when MAGAmedia try and tell Europeans that we shouldn't feel safe in cities from London to Malmo that you've never even visited.
