$ to buy the things you want and need.
$$ to get other people to do things for you
$$$ to get organizations and entities to do what you want
Levels are about what you spend your discretionary income on.The higher the level the wealthier you are.
Know what level your business is appealing to. If you are a service, your in level 2. If your selling widgets your level 1. If your a Political Action Committee, or own a pro sports franchise, your level 3.
I am a poor level one as I am primarily concerned with having enough money to buy things I need and want. A more financially secure person is primarily concerned with having enough money to pay for services such as fine dining, vacation packages, and landscaping. The 3rd level of money is when you are so rich and have so many people on your pay roll you are primarily concerned with spending money to change policy, procedure or even laws.
There is possibly a 4th level that is philanthropic, but also legacy concerned as naming rights are sure to be involved. The Bill and Melinda Gates foundation is an example.
