The technology of blockchain and its aggressive popularization through rapid growth of prices for crypto-currencies can help the world financial system solve its main problem, which is the shortage of long-term financing, and ensure the subsequent global economic growth.
Nothing can help the financial system, it's doomed to fail with how it's set up. Bitcoin is no world-problem-solver. Bitcoin is just a layer on top of the current system, where everything below that layer is rotten to the core. People are supposed to hedge that rotten system by using Bitcoin, the government itself will just keep sinking down as hard as always, don't let them take you down with them.
Their motto is debt = good; why do you think the majority of the people became way poorer throughout the years, and the rich became richer? You as debtor are filling their pockets. It's not just a way to control people, but also a way to conveniently make sure that capital from you keeps shifting towards the elite.
Simple life lesson; if you can't pay for something yourself (ie, with your own money), then don't buy it. You'll thank yourself for that later on.
