If there was on thing I learned with this crises is that services are the first to go down. Why? Because they're expensive and not a must have.
On the other hand real products like food, houses, vehicles, medicine... are the ones that will never go down (must have). But they have low margins and are not so attractive during growth periods.
So while the trends exposed here are probably true, the fundamentals will surely change with such large disruptions as the ones predicted here. And then the service providers will not have who to sell to anymore. Auto-balance
