In the US, the stock market is much bigger part of the economy than anywhere else in the world.
True, but that doesn’t make it big. Way less than half of Americans have any meaningful wealth invested in the stock market.
If stock markets collapse, companies collapse and lead to large scale job losses, people's 401k make them look so poor. So that is enough rationale for the Fed to buy up stocks to prevent that scenario.
Not really. We’ve seen lots of stock market corrections that have had absolutely no material impact on the real economy. Those are terrific events for cash rich companies — and there are lots of them now, and more cash rich than ever because their bond portfolio just spiked — to go buy their own shares and make acquisitions. Private equity loves these events, too.
No, you still need events in the real economy to have real impact. And the 401(k) and IRA plans are stabilizing factors, actually.
A contagious virus is actually good short term news for workers, would you believe. Employers in a tight labor market are suddenly reminded that they need (healthy) employees, and the virus both boosts labor demand (especially in healthcare) and reduces labor supply in the short term. Most employers are reluctant to lay off workers amidst a public health crisis in a tight labor economy because that’s just bad for business. So I don’t think we’ll see consumer demand fall much in the aggregate. Indeed, it might go up.
