What couldn't I bought?

I fell into the deep thought,
What could not I bought?
I questioned one and more,
But nobody answered from deep core.
At last the solution came into my mind, which I can not anywhere find.
I want a a world of my dreams which-
not use the difference between poorest and rich.
I want a world better,
I want to live with my dreams together.
Where I can achieve my own aim,
Where I don't have to run for money and fame.
