Sounds a lot like the democrats estimates on the cost of Obamacare. Heck, that pretty much sums up every estimate the federal government has come up with for pretty much every healthcare program they've implemented.
Nobody should be surprised if the expansion of government workers is larger than predicted, and nobody should be surprised if 250 billion annual cost of Obamacare is, hrm, underestimated.
Can you show evidence they are hiring 16,000 new IRS "agents "?
