About how inflation plunders the poor, this should be the best explanation! You cook 10 bowls of porridge, and someone adds a bucket of water, taking away 90 bowls, leaving you with 10 bowls. You seem to have no loss, but in fact, your 10 bowls no longer have the same filling as before. Someone's bucket of water can make 90 bowls, and they continue to sell. To put it simply, inflation is that your money is earned, while their money is printed. When mixed together, your money depreciates.
