What is a harsh expectations vs reality people aren’t aware of?

Expectation: That you can work hard and get ahead in life. Reality: That hard work doesn’t always pay off. You can work your ass off and still not make enough money to get ahead. It’s like running on a treadmill – you’re working hard, but you’re not actually going anywhere. And even if you do manage to get ahead, there are often systemic barriers that prevent people from staying ahead for long.
