Um, no.
Detroit doesn't have a "corporate tax" to raise. And neither does it have a progressive tax on property with one rate for the poor and one for the rich. Just like everywhere else, people pay a percentage of property tax based on the value of the property, not on their income bracket.
I don't know what the national average is, but in the rural area I volunteered in, estimates ranged from 25-35% of adults. It wasn't a terribly poor area, either.
I'll bet though that rates in affluent urban and suburban areas are much, much lower than that.
