How is the rise of the one percent relevant when discussing increasing inequality in the united states?

a) the impoverished unfairly blame the one percent for earning so much more money than most citizens in the united states so they do not have to change their own behavior.
b) the disproportionate wealth of the one percent reflects the increase in compensation offered to executives and high-level managers compared to the working class.
c) the wealth of the one percent has been spent disproportionately on luxury goods as compared to philanthropic and charitable pursuits, leaving the lower classes to fend for themselves.
d) the government incorrectly assumes that the one percent will voluntarily pay higher taxes, and so the amount of money the government needs to support social welfare programs is consistently underestimated.
