And even if the country isn't broke, the principle still stands; if you put the tax burden on those who can least afford it, they pay it by cutting back on what they spend on consumer goods and services, which slows the overall performance of the economy.

Furthering on that, by placing the civil burden on those with less income reduces the amount of taxes areas have to deal with, so like any industry, they need to find other sources. Those sources then seem to target the ones in the worst position to be able to afford it. Example: Heavy fines for speeding and other traffic violations in poorer neighborhoods. Look at the state of Ferguson, MO which was just analyzed in great details. Something like an average of 2.7 warrants per person because they don't appear in court to be able to afford fines.

We are making criminals out of vast oceans of people because a few people at the top don't feel much like paying a fair share of the taxes.
