Investment doyen Warren Buffet said ultra low interest rates around the world were great for the financial returns of companies, but he lamented how easy money policies of central banks “destroyed” pensioners and other savers.
“With practically zero interest rates, American business is earning terrific returns on tangible equity,” Mr Buffett said.
“They have not suffered even as people on fixed interest instruments have suffered enormously.”
His remarks to 40,000 shareholders at Berkshire Hathaway’s annual meeting in Ohama, were the billionaire’s latest shot across the bows of low and negative interest rates employed by central banks in the US, Europe and Japan.

“The system works very well in terms of aggregate output,” he said.
“In terms of distribution of that output it can fall very short in my view.”
“But it will keep working, you don’t have to worry about that.”
“Twenty years from now there will be far more output per capita in the United States in real terms than there is now.”
Still scarred by the 2008 global financial crisis which caused household incomes to slump for years, polls suggest many Americans are fearful of the next generation being left worse off than their parents and grandparents

“They’re wrong,” he said.
Pressed by a shareholder about the prospect of a Donald Trump presidency, Mr Buffett said: “No presidential candidate or president is going to end” the economy.
