Hi Qara, the followings are my suggestions regarding your writing.

Overall, the flow of your writing is definitely confusing as well as its sense of meaning

There are some minor errors I found:

-happines is depends happiness depends on
-some people feel happines some people feel happy, Happy/adj./, Happiness/n/
-if they have buy a luxury carsif they have bought a luxury car/luxury cars
-a children plural:children, kids/singular:a child, a kid

Thank you. keep practicing.
