It's actually a tax on those who hold money, especially the middle class. Rich guys have investment portfolios, hold gold. The poor spend everything they get every month, so they aren't affected that much, but the middle class, the people who have some savings, but not enough to have a stock portfolio or a number of real estate properties, have to pay the tax.
Inflation is just another form of taxation. Diluting the money supply makes everyone who holds it lose and makes all other assets gain value against the currency.
I'd use my emergency funds if I were you, but don't go to 0. When you're down to whatever you earn in a month, it should be a sign that you're getting into dangerous territory and better start looking for another job, or a property to sell. Maybe you have a spare room at home? Maybe you have 2 cars and could manage with 1?
