If Bitcoin becomes the world's reserve currency, it could change the world. The daily price of goods and services is decreasing. This will lead us from an inflationary to a deflationary economy. The exact opposite of what we see today!
I'll contend there is nothing intrinsically flawed in inflationary economic models. Both deflation and inflation have roles they are uniquely suited to fill. They're different tools useful in different circumstances.
During the Great Depression investment banks gambled and lost with the money of depositors. This lack of separation between commercial banking and investment banking was blamed for the melt down. As a result certain protections were implemented to prevent investment banks from gambling with the money of depositors.
These protections rolled out in 1933 were known in the USA as glass steagall.
Where the US inflationary economy began to go wrong is when glass steagall was repealed in 1999. Less than 10 years later a banking crisis would emerge.
