Chicago and New York City has MORE " urban sprawl ", because of immigration, since 1970 ? Not that I know about. Chicago's " sprawl ", since 1970, has been upwardly mobile and empyt-nester fed. So has New York's been. The gentrification of both Chicago and all five boroughs of N.Y.C.,still has most immigrants, legal and otherwise,living in slums, just as they did in the early part of the 20th century and before.
No, actually, I take that last bit away. Slums were built and expanded upon, in Manhattan, in the mid to late parts of the 19th century, so, yes, immigrants did, indeed, add to Manhattan's " urban sprawl "; just NOT since 1970!
The word suburb is a misnomer for any of the quiet towns and farming communities that have been transformed into small cities by legal and illegal immigration in the Chicagoland area, now.
Look at Bolingbrook, Aurora, Desplaines, Buffalo Grove, etc.. What once were corn fields would now be considered urban areas in other parts of the country. They're all cities in their own right, now.
A friend recently told me that the last farmer in Desplaines sold his land, in the area of Rand and Golf roads, to a developer. He had stubbornly held out for decades in spite of the city that went up around him.
All of these little cities surrounding the big city of Chicago have seen their property taxes skyrocket in order to provide services to the families of legal and illegal immigrants.
Elderly, retired Americans have been forced to sell their family homes in these areas, because they can no longer afford to pay the skyrocketing real estate taxes that are necessary to support all of these new immigrants and their families.
The open-borders, one-worlder, pro-amnesty RINOs don't give a damn about the plight of these American citizens that have worked hard all of their lives and are now on a fixed income.
These new immigrants can afford the property taxes, because they live 20 to a house. They're turning single family homes into tenements in what used to be the suburbs of Chicago, too.
