(CNN) - In his most critical comments to date of the Obama administration's policies, former President George Bush Wednesday warned against the nationalization of healthcare, government overreach in the country's financial system, and the potential effects of closing the terrorist detention center at Guantanamo Bay.
"I know it's going to be the private sector that leads this country out of the current economic times we're in," the former president said during a speech to business leaders in Erie, Pennsylvania, according to the Washington Times. "You can spend your money better than the government can spend your money."
"Government does not create wealth. The major role for the government is to create an environment where people take risks to expand the job rate in the United States," he also said in the closed-door speech, according to the paper.
During the remarks — one of Bush’s first in the United States since leaving the White House - the former president commented on a wide-range of issues currently confronting the Obama administration, including the new president's push for universal healthcare.
"There are a lot of ways to remedy the situation without nationalizing health care," Bush said. "I worry about encouraging the government to replace the private sector when it comes to providing insurance for health care."
Asked directly if he thought his successor was embracing "socialist" polices, Bush stopped short of weighing in one way or the other, instead saying: "We'll see."
In a vigorous defense of his own national security policies, the president appeared to take issue with the new administration's early decision to close the detention center in Guantanamo Bay and ban the use of aggressive interrogation techniques.
"I told you I'm not going to criticize my successor," he said, according to the paper. "I'll just tell you that there are people at Gitmo that will kill American people at a drop of a hat and I don't believe that persuasion isn't going to work. Therapy isn't going to cause terrorists to change their mind."
Bush, in contrast to former Vice President Dick Cheney, has largely remained silent on the new administration's decision to prohibit the use of so-called enhanced interrogation techniques. But during his speech Wednesday the former president insisted he used "every technique and tool within the law to bring terrorists to justice before they strike again."
Bush also appeared to take a broad swipe at the tone of American politics in general, noting that partisan vitriol dates back to the founding fathers when Vice President Aaron Burr shot and killed Alexander Hamilton.
"At least when my vice president shot somebody, it was an accident," Bush said.
