Pension Funds and Corporate Bailouts

What if one of the candidates came up with a plan to require companies to fully fund their retirement plans and offered a matching plan of federal funding for companies who did so for a period of time. Would this help some of our auto manufacturers and legacy airlines who are having trouble competing with Toyota and JetBlue, who are not burdened with expensive health and retirement plans? Wouldn't this use of Federal money be better than traditional welfare and corporate welfare? Might it someday take some of the pressure of Social Security?
