Why do current economic and corporate structures tend to reward short-term profit extraction over long-term trust, care, and customer satisfaction, even when the latter can generate lasting value?

A very general question, but what happened to being wholesome and community/customer-driven? Companies built themselves on customer trust and quality products but now we're just fed marketing. Even the companies that built that trust are doing this... The populace seems to be buying this strategy and I'm just genuinely confused.
