Summary
This quote implies that money can serve as a means of accessing and purchasing goods and services, much like a credit card, but it is limited in its functionality. The comparison to a "poor man's credit card" suggests that money is a less effective or less convenient tool for financial transactions compared to a credit card, which offers more flexibility and options for purchases. It highlights the idea that relying solely on money can be constraining and less advantageous in today's digital and credit-based economy.
