Anyone who wondering why health care premiums are exploding just needs to take a look at the insurance industry.

Schumer pointed to the profits of the 10 largest insurance companies — which shot up 428 percent between 2000 and 2007, from $2.4 billion to $12.9 billion — as a reason health care reform is needed.

The insurance industry has not been playing ball on reform, and now Senate Democrats are getting fed up.

With other industry groups pledging savings to help pay the cost of health care reform, Senate Finance Committee Democrats slammed insurers for holding out — and threatened to impose new fees on the industry that could cost it as much as $100 billion.

The Finance Committee members are currently hunting for hundreds of billions of dollars to help finance reform, and with the hospital and pharmaceutical industries having pledged $235 billion, the senators said it was time that the insurers paid their share.

“We need the insurance companies to step up to the plate and be part of the solution. Most of the negotiations so far, the insurance industry has been at the table but you can only sit there at the table with your arms crossed for so long,” said Sen. Chuck Schumer (D-NY).

Schumer and Sens. John Rockefeller (D-WV), Debbie Stabenow (D-MI) and Robert Menendez (D-NJ) pounded the insurers, who they portrayed as unwilling to help pay for reform even while they have enjoyed exploding profits.

“The insurance companies are the people who are just rapaciously, greedily and unstoppably making money by underpaying the patient, by underpaying the provider and by overpaying, therefore, themselves,” Rockefeller said.

We’re seeing a new urgency from the White House and other Democrats on the health care reform issue, and it’s refreshing to see them ratchet up the pressure on the insurance industry.
