People who own a cash register live better. If you don't have a cash register, you are working for someone who does. That's how the system works.
A cash register means: someone comes, pays money, buys something, and leaves. And they can come again. Ideally, they come even while you are sleeping. After that, things get easier.
This isn't about being greedy. The ideal situation is simple: the cash register should be yours. Instead of working for someone who owns one, you own it. And if you can create something that benefits humanity—even better.
