Doesn't this depend on the company? Demand for agriculture, petroleum, and financial services (among many other things) are fairly inelastic. People are going to consume all of that stuff regardless of how financially well-off they are.
Demand for agriculture is inelastic, but I don't think the same of petroleum or financial services.
Without travel, demand for petroleum has dropped significantly, to the point it was below 0 for a short time.
Financial services can come to a screeching halt as well if people stop buying on credit or taking loans out on housing and cars. Maybe I'm being short-sighted in only considering the consumer aspect here.
