So, this statistic could mean that these counties have proportionately more low income workers that they did, but it doesn't necessarily mean that the higher incomes dropped (inflation adjusted)
It also means that some areas that used to be rich now probably have a much better supply of people to mow lawns, flip hamburgers, etc. But, social services, education, police departments, must be impacted by the influx. These rich counties can't have it both ways...maybe the silver lining here is that those who "benefit" from low income immigrants will see the objections most sane people have, now that it's impacting their own towns!
Norwalk was NEVER anything but middle calss !
Stamford has been a "mix " , for decades.
Wanna try to talk about a subject you actually KNOW something about ? : - )
