It has everything to do with it. The ultra elite pay no income tax because they don't have jobs. Rather they pay capital gains which until recently was 15%. I am not arguing in favor or increasing capital gains but rather going to a consumption type tax. A silly flat tax is based upon......income.
i have no problem with a consumption tax since that way you would get all the black market criminals paying into the system that as of now pay nothing either, get some of that EBT money back as well
