Americans are not feeling better about the economy, Forbes Media Chairman and two-time Republican presidential candidate Steve Forbes said Thursday.

"You see the anger out there — angst about the economy, worry about the security of this country," he told CNBC's "Squawk Box." "People aren't worried about income inequality. They want growth in their own income."

In a new book, "Reviving America," Forbes is calling on GOP presidential candidates to adopt "radical" pro-growth initiatives, including repealing President Barack Obama's signature Affordable Care Act, implementing a flat tax and reducing the Federal Reserve's influence over monetary policy, CNBC reported.

"The candidates, many of them, are moving in that direction, but they have much more to do in terms of how you replace Obamacare," he said. "On the tax side, you've got to make some tweaks into their various tax proposals."

Forbes said only Sen. Ted Cruz of Texas and Sen. Rand Paul of Kentucky have been willing to tackle the central bank and its "disastrous" policies. Those policies have "gummed up" the credit markets and created "lousy" labor markets, he said.

He said the Democratic mantra is, "We've got a punk economy. Don't think about getting ahead. We'll just help you out a little bit, but don't think you can have a better life."

So, what should investors do?

"The best thing that 318 million Americans can do about that danger is to tune out every single word that politicians have to say about it," Newsmax Finance Insider David Stockman advises.

"That’s because for 99.99% of Americans the risk of being killed or injured by a jihadist lone wolf is lower than being struck by lightning; and most surely it is far less than their exposure to the periodic eruption of mass killings by homegrown psychopaths and demented malcontents that occur with disturbing regularity."
