The National Council on Aging has just posted a blog article regarding tax reform efforts in Washington. The article is significant and I recommend you read it here.
The article makes the case for the proposition that a) Congress knows that its tax reform bill will greatly expand the deficit (by giving large tax breaks mainly to corporations and the already mega-wealthy), and b) that when the deficit does increase, most normal Americans will not remember that the increase is due to this tax reform, and c) Congress will then lower that deficit by cutting social spending programs that benefit Seniors, like Medicare,
Medicaid, the Older Americans Act, and possibly Social Security.
