The justification for this scam of a tax bill is that the permanent corporate tax cuts will incentivize corporations to make new big investments spurring salary increases and new jobs.  And I keep reading articles that have company heads and CEOs claiming that this will in no way make them interested in doing that.  They’ll mostly use the breaks to do what they’ve always done: boost shareholder profits.  So I find it awfully bold for people like Paul Ryan to insist that corporations will absolutely do something that they have no financially good reason to do.
