Yes throughout the history there had been some ups and downs. But it’s mostly win win situation. Those who understood the assignment of business they fired it up and went up in the economic point of view and those who did not well they are just crying.
I think it’s all about what is our perspective when looking at money, how we earn, what we do, how much efforts we take for the same.
The rich oppress the poor, that's not new, the world is filled with oppressors. Government and citizens, men and women, Father and Child etc nobody that doesn't feel like they're oppressed especially when love is nowhere to be found. I've gone through some of the history behind the oppressed and realized that nothing solves the problem other than love; the oppressed showing love to the oppressor. As for bitcoin, it's money and can be purchased with fiat so, Op's idea is not solid since the rich can always purchase as many bitcoin as they could, if the world finance moves towards bitcoin. The rich work so hard to keep up their businesses and they use employees to execute menial jobs and take the credit when the job is completed or accomplished. Things only gets better if everyone focus and work towards their dreams instead of thinking of the stress they're subjected to by their master or boss whatsoever.
