ETH staking trends beyond a price point? Who gets pushed out over time?

Are there any publications doing trend analysis on at-home staking (not pooled, staking-as-service, or exchange mediated) once ETH hits different price thresholds, e.g. 1K, 1.5K, 2K …. 4K, 4.5K, 5K, etc

I would assume the percentage of at-home stakers (out of all stakers / validators) begins to decrease over time given the very nature of PoS, and the economics of ETH? Shifts more towards institutions?

My main question does the laymen (who stakes at-home, full node validator), get pushed out over time? I am just curious how this impacts decentralization in that future world when it becomes a little too cost prohibitive to do the “gold standard” staking as a regular Joe/Jane kind of person.
