Actually the hypothetical actors will have $200 and $55 respectively. To reinforce your point, if price of goods does go up 58%, the actor that started out with $50 will be 30% poorer in real terms (now having $55 and his $50 basket of goods now costing $79), whereas the actor that started out with $100 will be 26% richer (now having $200 and his $100 basket of goods now costing $158).
