I think one way of looking at the economic pathologies of our society, without using words like 'capitalism' and 'rentiership', is to talk about inequities in the distribution of risk. Some have more taste for risk than others, sure, but risk is not distributed on this basis.
In the UK, so much of our political troubles come from the growth in the landlord class, who if nothing else, wield disproportionate power relative to their social worth: at one and the same time claim to be martyrs to the risk of investment, and demand these risks be minimised.
Of course, it's possible to make claims like this: e.g., nurses have every right to claim that they shoulder not merely more risk than most, but far more risk than is strictly necessary. The pandemic has made this brutally obvious to anyone who has been paying attention.
However one chooses to tally up compensation for this social role, be it financial, social, or some other privilege, it's pretty obvious that every last 'essential worker' is shouldering more societal risk than most non-essential workers compensated far better than they.
The way this trade off gets (implicitly) articulated as 'pay vs. purpose' is one of the enduring insights of @davidgraeber's Bullshit Jobs. Yet there are many essential workers who don't even get the illusion of purpose in compensation for personal risk (e.g., warehouse staff).
