TL;DR: the modern Holy Grail is a subscription fee.
The basis of any person’s psychological comfort is having a fixed income. It allows to plan, make commitments, and not have to worry about meeting basic needs on a daily basis.
The most affordable solution to getting a fixed income is to sell your own working time in bulk. This solution even has a special name: salary.
A less affordable, but more pleasant solution is to receive a fixed income from the invested capital. In the form of dividends or other regular payments.
But the most valuable solution on the market is the fixed income business. Which is a service to subscriber customers.
Any business should endlessly strive to become the most powerful customer service department on the market.
