Please open a book and learn how compounding works. There are no "shenanigans" here, rather, widespread consensus that 2% inflation year on year is quite healthy, in spite of your disingenuous attempt to overdramatize it.
The "widespread consensus" isn't that "2% annual inflation" is healthy.
It is that it is the best way to increase GDP because it encourages people to invest rather than sit on funds. If we didn't have inflation, it wouldn't be an automatic tax (or mandatory enlistment) for the poor to trust their savings to the stock market. It wouldn't inflate the stock market above their actual value and cause additional risky investments and otherwise poor investments by the masses who wouldn't HAVE TO be a part of the system otherwise.
It isn't "healthy" for everyone. It certainly isn't healthy for people who have to take out money when the system is way down... Get over your anger issues. This isn't reddit. :)
