How has power or status given an unfair advantage over the people of the Valley of the Ashes or West Egg?
Need an example where either tom or Daisy use thier power to gain an advantage over their lesser priveleged citizens.
One clear example of this power dynamic is found in Tom's affair with Myrtle Wilson.
Tom is demeaning to George Wilson, his mistress's husband, who owns a garage in the wasteland between New York and East Egg.
As an independently wealthy man, Tom does not have to spend his time working like Wilson does. Wilson is stuck in his auto shop working to make a living.
This disparity leads rather directly to Tom's affair with Myrtle in the sense that Wilson literally does not have the time to watch after Myrtle. If Wilson was not forced to work all day by his financial status, he would be able to watch over Myrtle to a greater extent.
Tom takes advantage of this situation in obvious ways, using his free time to woo Wilson's wife and using his money to do it too.
Tom also keeps Wilson busy, hiring him to work on a car. This creates a subterfuge wherein Wilson feels grateful to Tom for the work and the income while Tom is, at the same time, taking Wilson's wife to an apartment in New York in an illicit dalliance.
