Tbf, this (low rate of return compared to other types of investments) can happen to PoW mining too but since PoW requires extremely specialized equipment, it is a lot harder to sell a mining stake. Mining requires long term commitment, staking does not.

To summarize this point: staking's primary cost component is financial. Therefore, PoS is a lot more susceptible to movement of financial capital & swings in interest rates than PoW, which requires large, upfront, long-term hardware investment.

Let me try to unpack this.
