In 2009 President Obama said his health care law would cost $900 billion over 10 years. Surprise! The Congressional Budget Office now estimates that the 10-year cost will be $1.76 trillion.
I think it is absurd and offensive that every law ends up costing drastically more than originally "estimated" by the politicians who pass it. The track record shows that the politicians are not making good-faith estimates -- they're scamming us. They're buying votes from favored constituencies with taxpayer money.
