"Apple of course has huge amounts of cash, but by the same token the cost of borrowing now is so unbelievably low that issuing long-term bonds ... is actually a very smart thing," he told CNBC's "Street Signs."

Schwarzman was speaking from outside the White House, where he'd unveiled Blackstone's plan to have 50,000 U.S. military vets hired over the next five years at the private equity group's portfolio companies, which together employ some 730,000, he said.

"Foreign investors are really very biased toward the U.S. now, largely because of the major change in the energy complex," Schwarzman said. "If the U.S. is going to be energy self-sufficient, which we probably are ... then this is a sea change and makes the U.S. an extremely interesting and important place to be investing. And it should increase over time our growth rates and our ability to hire people."

Noting that Blackstone is now the largest owner of individual homes in the U.S., he said, "We're renting those houses to people who really can't be in them in other ways. So I expect that housing prices will continue to go up and it's not really a bubble."
In China, he added, government policies are helping to bring the real-estate situation there under control. "Their housing prices have come down a lot already, and that bubble is on its way to being deflated," he said.
