I agree with the system you describe, i tend to disagree with the conclusion.

I suspect the size of the debt is just a "dc offset" and not the main signal. While important, maybe not as "information-ally" significant as it's size would suggest. Still it is probably hiding something, a subtle bug in the accounting, and that something contributes to the frequent cycles of debt-jubilees, revolutions, upheavals etc.

Now the real question you have posed is what is missed in the debate - most wealth in our society is captured in the make up and choice of goods and services consumed, and what is the contribution of a bias towards wealthy consumption here? e.g. in my country there were about 150 luxury yacht sales totaling ~$4billion, vs ~80,000 luxury car sales @ ~$15billion, vs total car sales of ~1,000,000 at ~$100billion. The annual cost of our public disability insurance scheme is ~$50billion. The "sharing" seems to have a significant access to resources compared to luxury on those accounts. I personally think the public disability insurance scheme causes harmful distortion to the broader economy while also meeting the important needs of some members of society.

My gut feel the issue is not ideological or political or a luxury preference, it's structural - the economy is not structured to deliver the correct set of needs, and this is due to real material constraints that have always constrained the economic problem. Not in terms that just the wrong top down decisions are being made, but that the correct bottom up decisions are prevented from being made. If you apply a model of computation complexity, feedback and iterative improvement - bottom up generally has more access to information and compute to directly address problems, while top-down can occasionally deal with global biases and accumulated error.

One true material constraint is the scarcity of competence and accountability. Wealth accumulation is the natural consequence of that material constraint. Top down "political & ideological decisions" are generally the enemy of competence and accountability.
