This is not true. When the inflation is high, normal savings accounts pay interest rate that protects from inflation. Besides if you are saving a lots of money you should invest it for something. Like government bonds at least.
> High inflation is rarely if ever matched by wages going up.
This is not true. Inflation and real wages are not connected. Why would they? See for example: https://en.wikipedia.org/wiki/Real_wages#/media/File:United_...
What high inflation does in some jobs, it allows employers not to lay off people by not increasing their wages (when their productivity is not increasing).
> Inflation penalizes anyone who isn't invested in things that hold their value versus the value of the money
And this is how it should be. Money should not be good store of value in long term.
And as I said before, savings account interest rates are not zero when inflation gets going. https://www.finder.com/history-of-savings-account-interest-r...
