Ben Levi,
The bill really doesn’t change much regarding end of life care. Most persons for whom such decisions must be made are currently covered by Medicare and this will not change.
The bill will improve things somewhat for those who are not insured. Currently, if you don’t have insurance, you don’t get end of life care — or any other kind of care other than emergency stabilization, which simply means that you are fixed up just well enough so that you won’t die that night. There are no halachic issues that the bill makes worse.
