Our private sector accumulated their wealth at the expense of the defenseless, the less fortunate, and the impoverished. Land was taken from the Native Americans. Ranchers and large farmers became wealthy off Native American land. Gold and uranium continue to be mined from land taken from Native Americans despite treaties that were supposed to protect the land. The railroads were built on the backs of immigrants (Chinese and Irish), who died by the thousands constructing the railroads under harsh conditions. The Mississippi Valley was cultivated on the backs of slave labor (primarily black), who died fighting malaria and other diseases prevalent in the humid, hot south. The wealth of the anti-bellum south was accumulated on the backs of black slaves kidnapped from their native homeland in Africa. The coal mine operators of Appalachia accumulated their wealth through land swindles that robbed local land-owners of their mineral rights and left a waste land in its place. The mines themselves were mined by immigrants (Welsh, Italian, Irish) and former slaves. The miners labored far underground in unsafe working conditions, so the wealth could be accumulated by the few in the private sector. The industrial revolution was built upon the backs of both immigrant and child labor. These practices continue today where the agricultural industry is heavily dependent upon the immigrants from Mexico and Central America. The private sector has even become too lazy to prepare their own own food, clean their own homes, wash their own clothes, and care for their own children. Instead, the private sector is content to take advantage of the less fortunate by paying wages below the poverty level and resisting any effort to share the accumulated wealth of this nation with the less fortunate.
As to where do the parents in LA and Chicago send their children? Since the private sector sits on their wealth and offers no jobs and no hope for the children of the impoverished, the children will end up unemployed, on welfare, and in the streets. It's no surprise that the impoverished, both immigrant and citizen, seek a better life for their own children. It's a moral tragedy, that so few seem to care.
