ah statistics. they do wonders for propaganda.
"Obama has already increased the IRS budget by 10 percent since he took office, to nearly $12.5 billion. The president's budget proposal for 2012 would increase IRS spending by an additional 9 percent _ adding 5,100 employees."
- from the article you quoted.
so that 10 percent increase should amount to a 125 billion revenue increase for the federal government, based on the 10 to 1 return rate you quoted in your OP.

oops. considerably less. so much for that statistic.
"Obama's 2012 budget proposal for the IRS includes $473 million and 1,269 new positions to start implementing the health care law."
oh, so the issue isn't really getting more money, but hiring more agents to enforce the health care law - something the GOP (and the public) feel negatively about. hmm, that's interesting.
now let's be frank - the issue isn't that the GOP is against the IRS because of some fictitious statistic. the issue is the GOP is against more taxation, and the health care law - which is what is driving the so-called increase here. another neatly omitted cost of healthcare that wasn't put into the total costs of the plan submitted to the CBO in the first place. shocker, that.
and if you REALLY want to focus on fixing the people skirting through on loopholes or avoiding taxes, etc., then simplify the friggen tax code in the first place to something consumption based. then you get everyone - criminals, tax evaders, cash only businesses, etc. but no, let's just whine about the current system and think throwing more money at it solves the problem.
while we're at it, let's sink another 100B into the post office, the rail system and fannie/freddie. they work just about as well.
