Part of the problem is defining "rich people".
To someone making $30K, $40K, $50K? Rich is $300K, $400K, $500K.
To someone who is legit rich? Multi-millions to billions rich? There's no daylight between $500K and 50K. We're all "the help" as far as they're concerned.
And, yeah, their wealth allows them to operate on a different level the rest of us just can't comprehend.
There are a few good books on the topic that everyone should read:
