Fact 1: reduced tax rate and revenue
Fact 2: permanent beneffit to corporations, in the form of tax reductions
Bet 1: the economy will grow
Bet 2: the proffits will trickle down
Bet 3: increase in economy will allow to fullfill obligations
If the bets do not materialize, nobody cares. That is, nobody except tax payers and recipients of federal promises.
Corporations and wealthy individuals will pocket proffits upfront. The rest are left praying for the bets to work out.
