So much poppycock
A key myth about the new law was furthered by Chief Justice John Roberts' ruling, which upheld the mandate under Congress' taxing authority. That same day, Rush Limbaugh called Obamacare "the largest tax increase in the history of the world."
Not even close, according to PolitiFact, which rated that a pants-on-fire lie. For starters, calling the mandate a tax doesn't change the fact that a small fraction of people are likely to owe it — since most who can afford insurance would rather have it.
The nonpartisan Congressional Budget Office estimates that about 4 million people will owe the penalty in 2016, paying an average of about $1,500 per household. The CBO says that 20 million people will buy coverage that year via the insurance exchanges — new marketplaces where even individuals with preexisting conditions will be able to buy policies comparable to what large employers provide.
Even if you add up every tax in Obamacare, PolitiFact says the total is comparable in magnitude to tax increases signed by President George H.W. Bush in 1990 and by President Bill Clinton in 1993, and smaller than one signed by President Ronald Reagan in 1982.
Pants on fire indeed!
