Republican presidential candidate Rick Santorum told the mother of a child with a rare genetic disorder on Tuesday that she shouldn't have a problem paying $1 million a year for drugs because Apple's iPad can cost around $900.

Speaking to more than 400 people at Woodland Park, Colorado, the former Pennsylvania senator said that demand should set prices for drugs.

"People have no problem paying $900 for an iPad," the candidate explained. "But paying $900 for a drug they have a problem with — it keeps you alive. Why? Because you’ve been conditioned to think health care is something you can get without having to pay for it."

The mother replied that she could not afford her son's medication, Abilify, which can cost as much as $1 million a year without health insurance.

"Look, I want your son and everybody to have the opportunity to stay alive on much-needed drugs," Santorum insisted. "But the bottom line is, we have to give companies the incentive to make those drugs. And if they don't have the incentive to make those drugs, your son won't be alive and lots of other people in this country won't be alive."

"He’s alive today because drug companies provide care," the candidate continued. "And if they didn’t think they could make money providing that drug, that drug wouldn’t be here. I sympathize with these compassionate cases. … I want your son to stay alive on much-needed drugs. Fact is, we need companies to have incentives to make drugs. If they don’t have incentives, they won’t make those drugs. We either believe in markets or we don’t."
