Please provide your reasoning.

Thanks in advance.

CONGRESSMAN: The wealthiest 20% of our national citizens contribute more than 70% of the total income tax revenues. This unjust burden placed upon high-salaried employees who through hard work and dedication have earned the rewards their talents command.

SENATOR: While it is true the wealthiest 20% of wage earners generate more than 70% of the total income tax revenues, the current income tax system does not impose a greater hardship upon high-salaried citizens than it does those with modest incomes.

Which of the following, if true, most helps to explain the apparent paradox in the senator’s comment above?

A. Large wage-earners generally have more opportunities to supplement their incomes through investments and tax-free accounts.
B. Many wealthy individuals have funds available to them is saving accounts that can be used to pay their income taxes.
C. The current tax code is based on democratically approved schedule of tiered rates that are applied to citizens accordingly to their total earnings.
D. Inherited fortunes, dividends and interests are all exempt from tax under the current tax system.
E. The economic disparity in this country is so great that the wealthiest 20% of workers earn 75% of the total income.

I would go with E though

yes, OA is E.
BTW, my answer was A as Anandk's with similar reasoning. but it's wrong.

So, Bhai please explain your reasoning.
