By Don Lee, Los Angeles Times Though sparse on details, the broad outlines of what Vice President Kamala Harris and former President Donald Trump want to do on taxes are clear — and they are very different. Trump’s tax proposals are tilted to benefit wealthy Americans and large corporations. Under Harris, the bulk of personal gains would come to those with lower and lower-middle incomes, according to the Penn Wharton Budget Model. “Harris has a more ‘coherent’ plan because she’s essentially got [President] Biden’s budget proposals, which are fairly scored, scrubbed and all that stuff,” said Douglas Holtz-Eakin, president of the conservative-leaning American Action Forum and former director of the nonpartisan Congressional Budget Office.
