Approximately 1/4 of Americans have no way to come up with $2,000 in 30 days. An additional 19% would need to pawn/sell possessions and/or take payday loans to raise $2,000 in 30 days.
I know I couldn't come up with $2000 in 30 days (I might come close if I sold everything I own). Does that make me poor? It certainly doesn't stop me from chasing my dream.
