The quote "If the stock market exists, so must previous lives" from Margaret Atwood's book "Good Bones and Simple Murders" suggests a deep connection between the complexities of modern life and the underlying histories that shape it. It implies that the structures and systems we engage with, like the stock market, are built upon experiences and events from the past, indicating that our current existence is intertwined with what has come before.

This perspective invites readers to consider how their own lives and the decisions they make are influenced by previous experiences, both personal and societal. Atwood's reflection serves as a reminder that understanding our present requires acknowledging the past, emphasizing the importance of history in shaping our realities and future paths.
