Comiconce, it's a shame that you are so bitter about the success of many of the people on this thread.
It is clear that hard work is a factor in their success, but it is t just about hard work. As many people have said, lots of people work hard in physically exhausting jobs and only earn the minimum wage. So there must be something different causing the wealth.
Qualifications are sometimes a factor in success. Many of the people on this thread have top degrees from top universities and are extremely clever. However, we know that lots of highly qualified, clever people earn very little or are unemployed. So there must be something different causing the wealth. You yourself have 3 degrees - you don't say what they are in or where they are from.....some degrees will be more useful for being in roles that bring in loads of money than others. Some will be more respected than others. Even with the most useful and respected degree (s) many people will never make mega bucks.
So what is it about? Whilst some people do have connections which help, many actually don't, as has been asserted on this thread. I think that it is simplistic and naieve to assume this must always be the cause.....and it is a way of abdicating responsibility....of saying they haven't contributed to their wealth and those who aren't wealthy haven't contributed to their situation either.
In the end, a combination of factors come into play to make people wealthy....as always, these things are never simple. Firstly, many of these wealthy people have unusual characteristics - they are extremely focused and driven (not the same as being hard working) so they can make strategic decisions at the crucial moments which make money. This isn't something which comes from hard work or academic qualifications necessarily. Secondly, as has been seen, they are often risk takers and prepared to live with risk and its potential negative outcomes. Most people are not like that and want to have security at the end of the month of a fixed pay packet and mortgage or rent paid. Again, it's a character trait and not really something acquired through lots of degrees. Notice that many of the wealthy are not employed, receiving a regular income, but running their own businesses, with all the risk that involves.
Another thing is the level of determination and refusal to give into knock backs. Along the way, most wealthy people have experienced bad times....but got back up. They haven't sat there and said 'it's not fair I'm in my 40s with lots of degrees and no chance of a career' but have fought to find a way forward. They never give up and believe there is always a way. Most people find it hard to get back up after knock backs. But for those who can, there is a much better sense of wealth. Some of them even seek the knock backs - they push the,selves to go out of their comfort zones, to seriously risk failure.
Another key feature is that they are problem solvers. So when there are problems with a project or problems with employees or problems with childcare at home ......they find a way forward. They make it happen.
One other thing I notice which I hadn't thought of before this thread, is just how many of them are in couples.....I don't recall many single parents on this thread. It means they have support and there are 2 adults to keep all of the plates spinning. While sometimes both partners are involved in the business and take the risks, or both have high powered jobs, others work it so that one works and the other looks after the children and domestic side. But certainly having 2 adults makes the juggling involved easier.
So, in the end I think being minted comes about for a variety of reasons. These people are hard working, clever, often highly qualified, sometimes with connections, but also highly motivated, driven, problem solving risk takers with a support network behind them that allows them to do the things necessary to make money. They have characteristics which most people actually don't. If you like, that's not fair......but there are lots of things unfair in life. However to think that they have gained their wealth purely through connections is daft and simplistic.
