Big Pharma just became Huge Pharma.Creating the world\u0026#039;s largest drugmaker—and paving the way for higher pharmaceutical prices—Viagra-maker Pfizer Inc. and Allergan PLC, which manufactures Botox, said Monday that they would merge in a so-called inversion deal worth up to about $155 billion.The takeover \u0022would be the largest inversion ever,\u0022 according to the Wall Street Journal, allowing Pfizer to profit from a lower corporate tax rate in Allergan\u0026#039;s home country of Ireland.The LA Times reported that the deal \u0022is likely to fuel critics\u0026#039; concerns that consumers would pay even more for drugs as competition declines among manufacturers, insurers and retailers.\u0022As Gustav Ando, research director for the business information and consulting company IHS Life Sciences, told the\u0026nbsp;Washington Post: \u0022This merger isn’t meant to benefit patients, it isn\u0026#039;t meant to innovate in any kind of way...and certainly the benefits won’t be passed on to consumers.\u0022Addressing this aspect of the deal, presidential candidate and U.S. Sen. Bernie Sanders (I-Vt.) said Monday that the merger \u0022would be a disaster for American consumers who already pay the highest prices in the world for prescription drugs.\u0022What\u0026#039;s more, Sanders added, \u0022[i]t also would allow another major American corporation to hide its profits overseas.\u0022While Pfizer cried poor in an effort to justify the merger—saying the U.S. corporate tax regime was forcing it to compete against foreign rivals \u0022with one hand tied behind our back\u0022—the coalition Americans for Tax Fairness showed earlier this month that the company had in fact \u0022dramatically overstated its corporate tax rates\u0022 and was already enjoying a significant competitive advantage over those who pay their fair share.And a Citizens for Tax Justice report released last month found that Pfizer has a stunning 151 subsidiaries in known foreign tax havens—more than all but five other Fortune 500 corporations.As U.S. Sen. Elizabeth Warren (D-Mass.) said in a speech on corporate tax reform last week, \u0022Only one problem with the over-taxation story: It\u0026#039;s not true. There is a problem with the corporate tax code, but that isn\u0026#039;t it. It\u0026#039;s not that taxes are far too high for giant corporations, as the lobbyists claim. No, the problem is that the revenue generated from corporate taxes is far too low.\u0022On Friday, the U.S. Treasury Department unveiled new rules aiming to curb tax-lowering inversion deals. But even at the time, analysts said \u0022there was scarce evidence they would stop the biggest inversion of them all, between Pfizer Inc and Allergan Plc.\u0022 The Obama administration has said Congressional action is necessary to eliminate corporate inversions for good.
