I guess we'll continue to disagree on this point.
I see your point, and I agree that some people must work harder, sometimes much harder, than others to achieve success (however the individual chooses to define it). As Mark Twain caustically remarked, the key to success in life is to choose your ancestors with care. In reality each of us is born with a unique combination of handicaps and talents, and it is up to us as individuals to evaluate them and make the best of them. For those who reject victimization and are willing to work toward their dreams, a large gap between rich and poor only means there is no limit to what they can hope to achieve.
In 1962, Time magazine ran a picture of President Kennedy at a baseball game in San Francisco and provided a quick biography of his host: born in southwestern Russia in 1906, drafted into the Czarist army at the age of 11 (!), the Czarist government quickly collapsed, Lenin took over and cut a deal with the Germans to cede a third of the country to them. The kid's home was on the other side of the line, and he decided not to go home. He hitchhiked 5000 miles down the Trans-Siberian Railway to Vladivostok, survived on odd jobs for couple of months, and got a job as cabin boy on an American ship bound for the west coast. He arrived in San Francisco, 13 years old, no friends, no family, and knowing just as much English as he could pick up in three months on the ship. 43 yeas later he was a multi-millionaire real estate developer with his picture in a national magazine beside his good friend the president of the US.
Granted that the story is anecdotal, but it is symbolic of the fact that our society places no barriers in the way of someone who is driven to succeed; we don't care who your parents were, we only care about who you are. A free market society rewards contribution, and it is the responsibility of each individual to find a way to contribute. About 80% of our millionaires are self-made, and they are the most generous people on earth when it comes to helping others climb the ladder.
