Here, although the ahistorical reading of Scripture by liberals on behalf of progressive taxation is hardly new:
Proportional taxes actually meet the equity and ability to pay principles of effective, efficient, and "fair" taxes. With a proportional tax everyone pays the same percentage but those who earn or spend more pay more. For example: if you buy a $50,000 car and the Fair/proportional tax is 10%, then you pay $5,000 in tax. If, on the other hand, you buy a $5,000 car, your tax is $500. By paying the same percentage, everyone is offered the dignity of being treated equally, and those who afford more pay more. Isn't that what liberals are always demanding?
"We have to raise the progressive tax rate so the "rich" pay their "fair share."
In reality, progressive tax rates, like the federal income tax, might meet the ability to pay principle but not the equity principle. Progressive taxes have varied tax rate percentages depending on income so taxpayers are not treated equally. Currently the top 20% of income earners pay more than 90% of the income taxes, while the bottom 50% pays less than 3% of the income taxes. Who's actually "paying their fair share?"
