Yep. Rich people can hire experts to validate and spot check their ideas, even write articles and what not about it. I wonder how much money do I need to be able to do that. A few things in the list that cost money are worth it if done at the right time. Tutoring with the the right resource can be the best investment sometimes and of course rich people will afford more of that.
Yep, $1M is not going to attract people to do things for you just because. The $50M+ people will have people flock to do small things for you for free.
I saw it with my old boss. People would always be asking if they needed help or would just offer free stuff in hopes of getting something later.
Correlation may not be causation though. Do people flock to him because he's rich, or is he rich because people flock to him? (or ... something in between?)
