Money attracts money, because we are open to the idea.
That's not why, IMO. Money attracts money because money boils down to "I can't be arsed with this shit unless you make it worth my while".
I could go into the theory of this - but instead, let me give you my personal history: I was born and raised in a pretty typical MC family and have followed a pretty typical path for someone like me: school, university, graduate trainee scheme corporate career, executive promotion.
I had jobs throughout my time at between middle school and graduation from uni. They were in customer service and none of them came with special perks.
Then I got hired as a graduate trainee by a flashy corporation. Suddenly, I found myself with an expense account corporate credit card, discounts on random crap and an employee stock scheme.
Then I was promoted to executive level. And suddenly I was being offered life insurance at a discount, business class flights, personal doctors, speaking slots at various events, random bloody people offering me silly amounts of money to take part in surveys, a free car, my flat being paid in full by my employer and private health insurance. Plus a whole bunch of other crap that I don't really care about.
And I'm not even particularly rich. I'm being paid an industry standard compensation + bonus package for someone in a highly paid industry at a senior level of seniority. I'm objectively speaking wealthy. I'm also light years removed from CEOs with base salaries in the 2-digit million range pa. In other words: I'm rich - but not obscenely so!
Money attracts money because, if you're already rich, people assume they have to bribe you into doing stuff that benefits them.
Nothing about this is about wishing for it or some other woo type stuff. People simply assume that you won't have time for them if you're already loaded unless they pay you.
The best method for getting stuff for free, in my own experience, is not actually needing stuff for free. Nothing spiritual about it, it's simply cold, hard capitalism.
