Little Ironies(Paper)
In the Paper, the irony of the story is "paper gains, paper house". When we buy stocks, the gains made is called paper gains for it the "money" is only on the certificate until we sell it to get real money. Thus, for when Tay Soon started buying stocks and gained money, he did not sell it and wanted even more. As a result, his dream house was also made of paper.
Stock is also like gambling, for it depends on your luck whether the stock prices increase or decrease. And once you start it, you cannot stop it.

The Rocking Horse Winner
The ultimate fault is himself. Paul had probably died from some sort of feverish exhaustion. He spent so much time riding the horse, and being obsessed about making money and being lucky for his mother, that he physically wore himself down. He didn't sleep or eat enough, and overexerted himself on the rocking horse. Thus, he died because of his own fault, for he had a choice to stop all these and did all these out of his own will. It was mainly because of his greed, or materialism that killed little Paul. His mother constantly sought out more and more money. Paul already sense that she "could not love" him, so, in his mind, he thinks that if he can be lucky, and make money, then she will love him. His desire to be loved was spurred on by her materialistic greed. Even when he does win money for her, it does no good. It in fact was detrimental to her, greed, she longed for more money. Even some might say it was her fault, but Tom in the end had the most power to stop what he was doing.
