Who is the "They"?

They said, work hard, go after your dreams. You worked hard and went after your dreams. They say there is a price to pay for everything. Nothing comes for free. So now you have paid the price. You worked hard, you gave your time, you worked hard to fulfill your dreams. They said you can't have everything. So now you have a fulfilled dream, but it has cost you time, the time away from your family. They say there is nothing like spending time with your family. You do just that but now you have no money. Then there are those who were doomed by their circumstances, by where they were born, the color of their skin. It didn't matter how hard they worked. They could have nothing. Their fate was decided by geopolitics, their race. They had no chance. Some will spend their entire lives in refugee camps. The moral of the "they say", "you need to give up something to get something, you can't have it all" is a bunch of BS. I haven't figured...
