Housing will eventually recover from its great swoon. But many real estate experts now believe that home ownership will never again yield rewards like those enjoyed in the second half of the 20th century, when houses not only provided shelter but also a plump nest egg.

The wealth generated by housing in those decades, particularly on the coasts, did more than assure the owners a comfortable retirement. It powered the economy, paying for the education of children and grandchildren, keeping the cruise ships and golf courses full and the restaurants humming.

More than likely, that era is gone for good.

“There is no iron law that real estate must appreciate,” said Stan Humphries, chief economist for the real estate site Zillow. “All those theories advanced during the boom about why housing is special  that more people are choosing to spend more on housing, that more people are moving to the coasts, that we were running out of usable land  didn’t hold up.”

Instead, Mr. Humphries and other economists say, housing values will only keep up with inflation. A home will return the money an owner puts in each month, but will not multiply the investment.
