The on-again, off-again “Gang of Six” has come back on the scene and is offering a “Bipartisan Plan to Reduce Our Nation’s Deficits.”

The proposal is quite similar to the one put forth by the President’s Simpson-Bowles Commission, which isn’t too surprising since some of the same people are involved.

At this stage, all I’ve seen is this summary (A BIPARTISAN PLAN TO REDUCE OUR NATIONS DEFICITS v7), so I reserve the right to modify my analysis as more details emerge (and since I fully expect the plan to look worse when additional information is available, the following is an optimistic assessment.

The Good

• Unlike President Obama, the Gang of Six is not consumed by class-warfare resentment. The plan envisions that the top personal income tax rate will fall to no higher than 29 percent.
• The corporate income tax rate will fall to no higher than 29 percent as well, something that is long overdue since the average corporate tax rate in Europe is now down to 23 percent.
• The alternative minimum tax (which should be called the mandatory maximum tax) will be repealed.
• The plan would repeal the CLASS Act, a provision of Obamacare for long-term-care insurance that will significantly expand the burden of federal spending once implemented.
• The plan targets some inefficient and distorting tax preference such as the health care exclusion.

The Bad

• The much-heralded spending caps do not apply to entitlement programs. This is like going to the doctor because you have cancer and getting treated for a sprained wrist.
• A net tax increase of more than $1 trillion (I expect that number to be much higher when further details are divulged).
• The plan targets some provisions of the tax code – such as IRAs and 401(k)s) – that are not preferences, but instead exist to mitigate against the double taxation of saving and investment.
• There is no Medicare reform, just tinkering and adjustments to the current system.
• There in no Medicaid reform, just tinkering and adjustments to the current system.

The Ugly

• The entire package is based on dishonest Washington budget math. Spending increases under the plan, but the politicians claim to be cutting spending because the budget didn’t grow even faster.
• Speaking of spending, why is there no information, anywhere in the summary document, showing how big government will be five years from now? Ten years from now? The perhaps-all-too-convenient absence of this critical information should set off alarm bells.
• There’s a back-door scheme to change the consumer price index in such a way as to reduce expenditures (i.e., smaller cost-of-living-adjustments) and increase tax revenue (i.e., smaller adjustments in tax brackets and personal exemptions). The current CPI may be flawed, but it would be far better to give the Bureau of Labor Statistics further authority, if necessary, to make changes. A politically imposed change seems like nothing more than a ruse to impose a hidden tax hike.
• A requirement that the internal revenue code maintain the existing bias against investors, entrepreneurs, small business owners, and other upper-income taxpayers. This “progressivity” mandate implies very bad things for the double taxation of dividends and capital gains.

This quick analysis leaves many questions unanswered. I particularly look forward to getting information on the following:

1. How fast will discretionary spending rise or fall under the caps? Will this be like the caps following the 1990 tax-hike deal, which were akin to 60-mph speed limits in a school zone? Or will the caps actually reduce spending, erasing the massive increase in discretionary spending of the Bush-Obama years?
2. What does it mean to promise Social Security reform “if and only if the comprehensive deficit reduction bill has already received 60 votes.” Who defines reform? And why does the reform have to focus on “75-year” solvency, apparently to the exclusion of giving younger workers access to a better and more stable system?
3. Will federal spending under the plan shrink back down to the historical average of 20 percent of GDP? And why aren’t those numbers in the summary? The document contains information of deficits and debt, but those figures are just the symptoms of excessive spending. Why aren’t we being shown the data that really matters?

Over the next few days, we’ll find out what’s really in this package, but my advice is to keep a tight hold on your wallet.
