American consumers, who spent a year watching Congress scratch and claw over sweeping health care legislation, can now try to figure out what the overhaul would mean for them.

The uninsured are clearly the biggest beneficiaries of the legislation, which would extend the health care safety net for the lowest-income Americans.

The legislation is meant to provide coverage for as many as 32 million people who have been shut out of the market — whether because insurers deem them too sick or because they cannot afford ever-rising insurance premiums.

For people already covered by a large employer — most Americans, in other words — the effect would not be as significant. And yet, just about everyone might benefit from tighter insurance regulations.
