Most of it comes down to short-term and long term view of people in charge. Unfortunately, companies do promote short term gains. Promo cycles are 1-1.5 years long for most companies, as a result people tend to optimize for launching. For managers, in FAANG, that seem to go around # of people that report to you, so they optimize for that. For a business, there's less incentive to do that investment. You need _some_ investment to keep it long term, but you don't need to put your 100% to make it work. It also comes down to VP of Engineering or equivalent in an org. Not overdoing technical debt is key. It's a means to an end, the end goal is still $$.
