1) The White House assumes 3% annual GDP growth, vs. 2% for CBO. That $21 trilllion in added GDP over the decade translates into $3.7 trillion in added growth revenues. They also (quietly) assume $1.4t in 2017 tax cut extenders.
(Domestic discretionary's proposed 1.6% of GDP by 2030 is even lower).
Should I tell them?
