Berkshire Hathaway Chairman Warren Buffett and Goldman Sachs CEO David Solomon address the biggest challenges facing the backbone of the American economy: the thousands of small businesses struggling with no sign of federal relief. “It’s an economic war,” says America’s best-known investor, about the uneven prospects of recovery for smaller firms. Buffett urges Congress to do something - now - and start with a new Paycheck Protection Program. “Just renew the PPP and get us to the end of the tunnel.” A bipartisan group in Congress released $908 billion legislation yesterday for economic stimulus. The proposal includes about $300 billion to support small businesses, a group exceptionally hard-hit by the economic slowdown of the pandemic.
