On Oct. 12, former President Bill Clinton appeared on the “Late Show with David Letterman” and urged “Occupy Wall Street” protestors to get specific, Politico reports.

“I think that, on balance, this can be a positive thing, but they’re going to have to transfer their energies at some point to making some specific suggestions or bringing in people who know more to try to put the country back to work,” he said.

Demonstrators from the “Occupy Wall Street” movement, which is currently in its fourth week, have protested against corporation bailouts made by the government, the economy and war. But Clinton said protestors must suggest specific political goals in order to see change.

“To make the change, eventually what it is you’re advocating has to be clear enough and focused enough that either there’s a new political movement which embraces it or people in one of the two parties embrace it,” the former president said.

Supporters of the movement have made their way to Washington, D.C. With tents and sleeping bags, participants have camped out in other major cities across the country—even after their demonstration permits had expired.

“I think what bothers people is the country has gotten so much more unequal under the last, over the last 30 years, and now that we’re in this fix, an enormous number of people have been out of work for more than six months, some of whom can’t get interviews because they’ve been out of work for more than six months, who always worked hard, always paid their taxes, did everything they were supposed to do, and made no contributions to the financial meltdown that caused their current distress,” he said. “I think that is the heart of what they’re saying on Wall Street.”

Clinton encouraged supporters of the movement to support President Obama’s $447 billion job package, which is being promoted to provide jobs for Americans.
