It could simply be that poor people don't complain about infrastructure projects like rich people too. Or they don't have the tools/connections to effectively stop it.
I imagine if you are renting a property, you are less likely to complain about things going on around the property because it's not your property to "defend." If you own (and especially if you are part of an HOA) you might be more likely to complain if there is construction going on for 3+ months in your neighborhood.
So it probably does fall into rich vs poor in the same way that renters may be less likely to be rich.
