The average American already has seen his total tax burden decreasing...
But I (and my corporation) just wrote out 7 tax checks in 7 stamped envelops to the government this April 15th, and woooiee! I didn't see a decrease. Nevertheless, national debt has to be paid back sooner or later, whether by inflation, currency exchange dropping, or by taxes, regardless of the future administration's political affiliation. A drop in tax burden now in exchange for a future increase is not reassuring.
