What is the social satire in the story happy event?

The main satire is addressed throughout the story and then reinforced at the end again; Ella is accusing this young servant of hers of murder and nothing less, when she too has committed the same crime. The only different that divided the two in their experiences was money and reasoning. This young girl is working as a servant, cannot afford to take time off or even afford to care for the child, none the less pay for an abortion. Ella on the otherhand can afford to take time off, can afford to care for the child and can afford an abortion. Lena, the servant, did not have a choice, but to take her child's life and Ella did have a choice, but she had made plans and they couldn't be interrupted. So, because Lena didn't have the means or funds she had to get her hands dirty and Ella let someone else get their hands dirty and allowed herself to forget the whole experience.
