President Barack Obama's plan to provide medical insurance for all Americans took a big step toward becoming reality Sunday after leaders of the health care industry offered $2 trillion in spending reductions over 10 years to help pay for the program. Hospitals, insurance companies, drug makers and doctors planned to tell Obama on Monday they'll voluntarily slow their rate increases in coming years in a move that government economists say would create breathing room to help provide health insurance to an estimated 50 million Americans who now go without it. The United States, unlike other developed countries, does not have universal health care. With this move, Obama picks up key private-sector allies that fought former President Bill Clinton's effort to overhaul health care. Although the offer from the industry groups doesn't resolve thorny details of a new health care system, it does offer the prospect of freeing a large chunk of money to help pay for coverage. And it puts the private-sector groups in a good position to influence the bill Congress is writing. Six major groups plan to deliver a letter to Obama and pledge to cut the growth rate for health care by 1.5 percentage points each year, senior administration officials said Sunday. They spoke on the condition of anonymity in order to sketch the offer before full details are revealed at a White House event scheduled for Monday.
