The fact that you're going to get a massively debased dollar back for each dollar you put in alone means it's a fraudulent process as it stands today (again due to our government's fiscal irresponsibility). The calculations used for inflation adjustments are about as bunk as you can get for govt numbers. The Fed has managed a catastrophic devaluing of the dollar over the last 50 years, and that's only likely to accelerate given their need to massively monetize our deficits and debts.
It is not related to fiscal irresponsibility. Sometimes it is due too too much demand and not enough supply driving the cost of goods up (prices are sticky) and other times it is due to underlying company costs going up and raising the prices to keep their profit margin even.
In neither case is it the government's "fault." Most governments around the world try to maintain an inflation rate of 2-3%. This is well understood. Don't keep your wealth in currency. No one sane has for over a hundred years even when we were on the broken gold standard (if you think inflation is bad, you should see what rapid deflation caused by a spike in gold demand followed by a rapid drop in demand does to an economy on the gold standard).
