I've seen tons of blacks be very successful in the Military. Both active duty and as working for the military as civilians. You can name any other race and the above still applies. I seen many discharged because they refused to become part of the team or just didn't try to improve themselves. Again, this pertains to all races.
Those who make bad decisions in life, fail to apply themselves, regardless of race aren't going to amount to much. Those who study hard, learn in school, work hard usually amount to something. Those who do not, usually don't. But each one has to make their own decisions, do I study or do I cut class or cut up in class or whatever. Do I run around with this bunch which is always doing the wrong things or do I stay away from them and try to better myself. Most folks regardless of race will rise to the level the apply themselves to achieve or sink to the bottom if they don't.
There will always be obstacles in one's path. Some will have more than others and a very few will have that silver spoon in their mouth. Some will work hard and find a way to either alleviate those obstacles or find a way to jump over or go around them. Others will sit down in front of the obstacle saying they had enough. Life is too rough. Race doesn't matter.
Some will blame the obstacles for their failures and do nothing to overcome them, others will try overcome them and those who try, try hard enough and long enough usually overcomes. such is life.
If you come from a culture of thieves, you become a thief. You value the attributes that make you a good thief. You learn. work at, being a great thief.
To use a baseball analogy, in the great baseball game of life, a disproportionate number of blacks are born at home plate with 2 strikes while most Americans are born on first base.
As to the military. I have seen many "losers" in life, forced to join the military and then thrive their. Why? Structure. All there needs are cared for by the socialist mechanisms of military life. It only goes to my point (in other threads over time) that each of us is unique and part of that uniqueness is out upbringing. Well meaning, very loving and dutiful parents in tough areas can often simply not know how to guide their kids to first base as they have been stuck at the plate their entire lives.
BTW, lose the "work hard" line. That is a load of crap.
Let me sum it up. If you are born at home plate and your parents are still at bat themselves, it is very hard to get ahead.
If you are born at home base and your parent have already been called out or worse, they have already been throw out of the game, the odds you will ever make it first are not very good.
A disproportionate amount of people who are slave descends are born at home plate with a strike. This as a direct result of slavery and the discrimination that followed and to a much smaller degree continues.
Until the average decedent of slaves, on average, start life on first base as do the majority, we have work to do.
Bear in mind, people go through obstacles in the ways they learn to. Like selling drugs at on the street corner while mom is driving the suburban kid to soccer practice. Who is more virtuous? The kid who's has no dad, mom is on crack and brother in jail so at 15 he goes to work in the system he was born into? Or the suburban kid bickering with mom over what to put in the car DVD player as they drive you soccer?
We have this idea that successful people are hard working and that poor people are lazy. My life has made VERY clear that this is totally BS.
