University of California at San Francisco apologizes for conducting medical experiments on prison inmates without consent

But the proposal that cleared a legislative committee in the state Assembly is still a long way from becoming law. It faces strong opposition from powerful business interests who say it would cost too much. And even if it does become law, voters would have to approve a massive income tax increase to pay for it _ a vote that might not happen until 2024.

Still, Democrats hailed Tuesday's vote for jumpstarting one of their long-stalled policy goals and signaling they won't back away from a fight even during an election year. In an hourslong hearing, some lawmakers and advocates assailed a health care industry they say has benefited corporate interests at the expense of consumers.

Ady Barkan, a 38-year-old married father of two, was diagnosed with ALS six years ago and now is mostly paralyzed. He testified at Tuesday's hearing with the help of a computerized voice that spoke as he typed using technology that followed the movement of his eyes. Barkan said he has battled his private insurance carrier to get treatment he needed, including suing them to get a ventilator that keeps him alive.

``Even good health insurance, which I have, does not cover the cost of the care I need to survive,'' he said.

To pay for everything, Democrats have introduced a separate bill that would raise taxes on businesses and individuals by about $163 billion per year, according to an analysis by the California Taxpayers Association, which opposes the bill. Voters would have to approve the tax hikes. Assembly member Ash Kalra, a Democrat from San Jose and the author of the proposal, said Tuesday it could be 2024 before that proposal made it to the ballot.
