I wondered how you could make this point and avoid downvotes.
"I thought everyone knew by now things are not what they used to be because everyone is trying to make more money."
People have always been trying to make more money. It's more that each corporation has more staff dedicated to wringing every last drip from the wet rag. e.g., the biggest supermarkets are most optimised and packed with marketing, loyalty incentives and more. Airlines pack in more seats, have in-flight shopping, etc.
"The sooner you get used to it, the better."
This point might've come across as "you have no choice." Probably more a matter of understanding the realities of finely-tuned capitalism and realising that you have choices. You can pay a premium for a better seat, for example. You can fly a cheaper airline and forgo checked baggage or in-flight meals/snacks.
