No company has the slightest clue what the economic environment will look like in 3 years, much less 5.
I dislike Amazon yet continue to order stuff at the same rate. How many non-government entities have a base like this? Seems like an enviable position.
How many layoff announcements have you seen where the company says "We'd love to keep pursuing this but we flat out can't afford to pay you, we are out of money"? I've seen zero. I understand some of this is prudent financial planning, especially for SMBs, but SFDC and AMZN.. they must be using different calculus.
Amazon appears less dependent on the nearly-free-money-gravy-train compared to most businesses, especially VC and startups.
