Pensions suffer the same issue too, I might add, unless you have an indexed pension like government workers. The reality is most of us will probably die from starvation in our old age due to not having any money, unless we manage to keep a job somehow.
That's the reality of inflation, folks. Back in the age of prosperity, when currencies did not inflate to the moon, it wasn't uncommon for people to retire in their 50s. It's a dystopian society if we are working people to death, especially when this is contrasted by all the Paris Hiltons and other capital owning parasites
The value of 401k's is based on the investments in the account. It is the goal of these investments to beat inflation. In 1914 the Dow Jones Industrial average (DJIA) was at ~71 (for rounding we can call it 100), as of yesterday the DJIA closed at 16851.84 (call it 16,000 for rounding). This is a return of 160x verses 60x for your soda example (from 5 cents to $3 at a bar).
This raises an interesting dilemma... When you assume it's free refills and they double charge you,
do you complain about the bill or let it slide?
Do you mean that the restaurant charges more then they have to charge me? In other words they could charge me $1.50 but charge me $3.00 instead. If this is the case then no I would not say anything as this is their posted price and I have the right to not buy the product (soda in this case) if I so choose.
If you mean that their price is $3.00 for one soda and the server put $6.00 on the bill, then yes I would absolutely say something. There is no reason to pay more for something that what I had agreed to pay. The server would likely be more then happy to remove the extra charge as if she wouldn't then the extra charge would likely come directly out of her tip.
