Reuters:  Romney & Ryan on Tax, by David Cay Johnston:

Together Mitt Romney and Paul Ryan have
put human faces on how the super-rich game the tax system to pay
less, pay later and sometimes not pay at all. Both want to
expand tax favors for the already rich, like themselves.

Their approach favors dynastic wealth with largely tax-free
(Romney) or completely tax-free (Ryan) lifestyles, encouraging
future generations of shiftless inheritors. What we need instead
is a tax system that encourages strivers in competitive markets,
not a perpetual oligarchy.

Romney and Ryan say that lowering tax rates and reducing or
eliminating taxes on capital gains and dividends, while letting
huge fortunes pass untaxed to heirs, will boost economic growth
and mean prosperity for all.

We already tried parts of that, starting with Ronald Reagan
in 1981 and doubling down with George W. Bush in 2001. Empirical
result: Flat to falling incomes for the vast majority, weak job
growth, but skyrocketing incomes for the top one percent of the
top one percent, including Romney. …

[F]undamental tax reform … honors the time-tested — and
therefore profoundly conservative — principle of making those
who gain the most from society bear the heaviest burden. Romney
and Ryan would shove that burden onto those with less, a radical
plan by an oligarch and his partner in promoting tax-free living
for the richest Americans.
