Not by you. obviously.
Lots and lots of African-descended Americans have taken advantage of the opportunities presented to them after 1955. If you look at metro DC, for example, there are thriving black communities everywhere.
However, there is a remnant of several millions, perhaps as many as ten million, who are not able to coexist with a modern society. Under segregation, they were mixed in with other black people (not "distinguishable", to use your word), but now that blacks have the mobility to escape from them, they are being concentrated in certain urban and rural areas where a distinctive third-world culture is emerging.
But if you cannot tell the difference between people who own their own homes in Prince Georges County and urban looters, you need new glasses.
Apparently you've never been to New Orleans or fail to see how unfortunate it is that those blacks who are in power have done little to nothing to help those they claim to represent.
The black leaders in Louisiana have so smothered those who really need the help that they have become indistinguishable from each other. This is unfortunate because there are many black groups who are doing a wonderful job representing their constituents, although they're never given the opportunity to shine publicly. Why? Because they are an embarassment to the so-called "black leaders."
