2008/9 was caused by years of individuals overextending themselves and the housing market game of "musical chairs", which was exacerbated by shady lending practices. None of those are in play here.
I think currently high unemployment and business activity was focused in the services industry. Even the airlines and aircraft industries are just getting started on their layoffs now in June. Debt defaults will start off with personal debt as in 2008. The trickle down effect this time will be trickle up, where those individuals will be changing their spending which will have a much bigger impact on the industrials like Boeing, Honeywell, United, American, etc in the coming months. Corporate defaults will probably start to appear in the metrics in the fall and accelerate.
