How I went from homeless to millionaire in a matter of minutes
From RAGS TO RICHES
The now rich man has bought an expensive sports car, hence emphaisising his ascent into the wealthy life.
The man is now also rich enough to buy a holiday, and this scene shows him on this holiday - relaxing and enjoying himself.
Since the once rich man is losing his money due to the fact that he was caught for fraud, he is seen kneeling in front of his former home in despair, since it has been taken away from him.
The once rich man, now with facial hair and unkempt clothes, is talking to a financial advisor, and tries to convince him to recover his bank account, however he is now declared homeless and broke.
The once rich man is now in the same position as the homeless man once was, and is sitting in the streets, being blatantly ignored by passers by. The now rich man also walks past. He gives the homeless man a second glance, and then walks off.
