A related point: Obama's SOTU made no mention of cutting corporate tax rates. Instead the president trashed the top 1 percent and slammed companies for keeping profits abroad and using unfair loopholes and deductions.  He's right about loopholes and deductions. Let's close them. But while we're at it, let's slash the corporate tax rate and make America more competitive worldwide. Obama kinda forgot the lower-tax-rate part, didn't he?  Also, nearly all studies show that middle-income wage earners are the biggest beneficiaries of corporate tax cuts.  Regarding those evil 1 percenters, according to the Tax Policy Center, the top 1 percent of Americans paid 33.4 percent of their expanded cash income in federal taxes in 2014. Meanwhile, Americans in the middle 20 percent paid only 13.7 percent of their income in federal taxes, while the poorest paid 3.1 percent.  You'd think a good class warrior like Obama would like these numbers. Apparently not, but why?  Read MoreHot topic for the 1 percent at Davos: Inequality  Quite simply, he wants more money for government spending. A partial list includes more spending on child care, sick leave, equal pay, lower mortgage premiums, a higher minimum wage, student-debt forgiveness, tax credits, and free community college. Some say this could wind up costing $500 billion.  So there's a lesson here for congressional Republicans and some of my fellow conservatives: Do not get sucked into this class-war politics. You will never outbid the Democrats on middle-class benefits. And take a cue from Ronald Reagan, who rejected class politics and argued that his policies would increase prosperity for all Americans.  For instance, Obama's child tax credits would be available for couples up to $210,000, tripling the max tax credit for childcare by up to $3,000. And that's very close to what some of my conservative friends want. But there's a better way.  Get rid of the 10 percent bracket and collapse the 25 and 28 percent brackets down to 15 percent. So if you're making $100,000 a year and paying $25,000 at the 25 percent bracket, your tax cost drops to $15,000 at the 15 percent bracket—that's a $10,000 savings. If you have two kids, with a $3,500 tax credit per kid, that's only a $7,000 savings.  From the lower marginal tax rates, the middle class gets a much bigger tax savings. With marginal rates coming down, the incentive effect kicks in as people keep more of what they earn. This way, all middle-class folks are included: married with kids, single women without kids, millennials without kids, etc.  There's still big savings for the kids we love and cherish. But it's done without class divisions, or the targeted tax credits that Democrats love. (My only exception would be an expanded earned-income tax credit, which would have a longer phase-out period so as not to penalize folks moving from welfare to work.)  Former CEA chair Glenn Hubbard has argued that "free community college, an enhanced tax credit for child care and higher taxes on high-income earners and large financial institutions" will not generate "growth, work, and opportunity."
Rather than name-calling President Obama's proposals, Republicans must draw a line between their worldview and his lack of economic sense.
