The way I look at it is that bitcoin fixes this is not wrong but also is to simple.
If bitcoin destroys fiat many things will no longer have the high time preference influence.
Removing fiat is like removing a contamination in your body. We are probably not even aware of all of to negative impacts of fiat. I suspect the affects will get worse before they get better.
So bitcoin doesn't fix everything as much as it replaces a destructive force in society and culture.
