Gender Balance: A Hypothetical Question

[Rain Man]

Biologically, we tend to have roughly equal numbers of males and females throughout our lives. Babies are slightly more likely to be male, but then they fall earlier to illness, kickboxing, and electric poles, so in adulthood we have roughly equal numbers of males and females. Then once you get past 40 the women become more common since they live lives of leisure and comfort in their corsets and bonnets while the men dig coal and chop wood and kickbox. However, the ratio doesn't really get extremely out of whack until the age of 70 or 80 when the men are mostly dead and the women are watching Court TV.

But what if it was different? How would society be different if one gender was notably less common than the other? I'll propose two scenarios, and let me know how you think the world would be different if...

Scenario 1. The ratio of men to women was 8:1. In other words, there were 8 men for every woman.

Scenario 2. The ratio of women to men was 8:1. In other words, there were 8 women for every man.

How would the societal power structure be different? Family structure? Sports? Housing? Leisure? What do you think?
