If it is praxeologically possible for even one to climb up the ladder, then it is possible for everyone.
some don't.

The point is it is not reasonable for the great majority of people to consider being rich as a likely possibility when doing their voting.  Hence, they should vote for an economic system at least as left-wing as, say, Sweden's.

But in America there are many millions of people who have found a very comfortable existence in the middle class.

The middle class was a political creation, caused by liberal policies like unionization, wage and work rules, and redistributive government programs, chiefly in education, housing, and pensions.

What mobility there used to be from poor to middle-class was largely achievable due to liberal redistributionist social programs in the area of educations - State school and student aid/loans, as well as income-boosting liberal programs like unionization.

No.  But I do dislike most aspects of America.

The bottom line:
In order to be rich you should be born to rich parents.


BTW: Unlike H.Ford - R.Perrot and B.Gatez have never been poor.

Once again, the facts don't support your story. 

Perot started out in life getting admitted to the US Naval Academy (which is free) and working as a commission salesman for IBM.  There was no family wealth.

Bill Gates family did have some and were possibly upper middle class; both parents worked.  They were not the super rich and their earnings wouldn't guarantee William III would be set for life.

More Horatio Alger stories.  Gates senior was an attourney, but a millionaire many times over.  The family had been wealthy for generations.

A recent study of U.S. millionaires found that 80 percent acquired their wealth in a single generation, without the benefit of inheritances.

Probably less amoung the super-rich.

Correct.  Nowadays, anyone that owns a home in an upper-middle-class neighborhood of the first-world parts of the US is a millionaire.
