President Joe Biden seized what may be his final opportunity to reshape Americans’ grim views on his term as he delivered a farewell address to the US on Wednesday night. Speaking from the Oval Office as he prepares to hand over power to President-elect Donald Trump, Mr Biden sounded the alarm over the accumulation of power and wealth among a small few. “Today, an oligarchy is taking shape in America of extreme wealth, power and influence that literally threatens our entire democracy, our basic rights and freedoms, and a fair shot for everyone to get ahead,” Mr Biden said, drawing attention to “a dangerous concentration of power in the hands of a few ultra-wealthy people. Dangerous consequences if their abuse of power is left unchecked.”
