Well, the tax cut didn't boost the economy, so no reason for the top few to keep benefiting when it was said that doing this would generate more tax revenue because the wealthy would spend, invest, do company crap more, etc... if they are taxed less, which wasn't true. So it's logical not to allow them to keep the benefit.
Reagan insider thinking taxes should be higher.
