I talked to an ex Remington engineer who now works making cartridges, about changes in firearms design.
About the year 2000, firearm companies took a good look at how much use their firearms were getting, and when it came to bolt guns, they came to the conclusion, the customer was not shooting that many rounds. And that the customer wanted cheap rifles. So weapon design is emphasizing price point over durability, maintainability. The customer gets something that goes bang for the least price.
Designs such as the pre 64 M70 and Rem M700 were based on considerations such as the barrel being shot out and replaced, trigger components lasting basically forever, etc, etc. Pre 64 M70 were an expensive rifle to build in its day, the Remington M700 cost less to make, but both are still expensive in comparison to the designs since 2000.
If you want more, you can still pay more. But that is not the market trend.
