Life is a personal journey.
Death is the end of all living things and even "the rich" die too!
Your conception and birth were out of your hands. You can ask your parents why they wanted to have children.
However once you are here the goal is to make the most of your life through learning and gaining experiences that enrich your life as well as others.
Who is to say that (you) can't become rich?
No one ever got rich without directly or indirectly enriching the lives of others! Even if you bought a winning lottery ticket the owner of the gas station, liquor store, or grocer would receive a percentage for selling you the winning ticket.
Rich people usually create companies which create jobs which allow employees to earn money to buy food, cars, homes, clothes, pay for the education of children, in addition they give away money to various charitable organizations. Not everyone who is rich was "born rich". Lots of rich people are self-made!
Some people lack the courage to pursue their dreams, others give up before realizing their dreams, and still others have no desire or inclination to pursue becoming wealthy. They're happy with picking up a paycheck.
What you decide to make of your life is up to you!
If there were no such things as entrepreneurs we'd all have to live off our land, grow or hunt our own food, build our own homes from cutting down trees with tools we'd have to make, make our own clothes and so on.
The exchange of money for goods and services improves all of our lives. There is nothing stopping you from coming up with an idea, product, or service that others would pay for. Having a "slave" mindset makes you bitter.
Even poor people have moments they're grateful to be alive! Take a stroll along the beach, a walk through a park, watch or listen to the performances of talented individuals, traveling, meeting someone special and falling in love are all things most of us can enjoy in life.
The world may not owe you anything but (you) owe yourself the world!
Life is what (you) make it! Make the (most) of your time on earth!
