It’s a little dance called capitalism:

1. Company becomes publicly traded.
2. Shareholders invest in the company.
3. The company aims to maximize profit.
4. Growth eventually slows down because almost everyone who could use the company’s services already does.
5. Shareholders expect returns on their investment.
6. To increase revenue, the company must either raise prices for customers or reduce operating expenses.

Money. No such thing as “enough” when you’re a corporation.
