Congress' last major tax overhaul, three decades ago, was everything this year’s version isn’t. The Tax Reform Act of 1986 won bipartisan support. Its benefits flowed more to low- and middle-income taxpayers than to wealthy individuals and corporations. And it added nothing to the federal deficit. None of that can be said for tax-cut package the Senate passed after the House approved a similar version. (AP Photo/J. Scott Applewhite, File)
