They are used by the rich. That's the thing they have in common. For instance, banks make billions on overdraft charges. Billions
This is something the rich never pay, but it keeps the bank running, protecting their wealth. Used. Donald Trump told us...he works hard to not pay taxes. Middle class can't do that. So, while we need money to run this country-- roads, airwaves, hospitals, schools, military,etc...the rich have Cayman Island and tax loopholes, middle class pays to make up for their dereliction of duty. This is why Buffet said his secretary pays more taxes than he does. Its a country, not a country club! And that includes Bernie Sanders, who pays 13% on 200k. The poor? The poor don't pay income tax, but they pay FICA. They pay each time they buy something taxable. And anyone who would like to live on poor peoples wages, thinking they have such a good deal...have at it! Yes, the middle class and poor have a common enemy....a system rigged against them.
