Financialization, in this context, refers to the process by which financial results, especially those legible to capital markets, exert pressure on the upstream industrial/corporate processes and inputs that produce those financial results.
"Excessive" or "obscene" or "pathological" financialization is when that feedback loop or reverse pressure ends up producing negative impacts on industrial/corporate processes, often in pursuit of shorter term positive effects on the financial results.
The exact mechanisms of this have been extremely well-documented in the numerous reports created in the wake of the 737 MAX failures.
Could you try leveling a substantive response now instead of a chain of strawmen and associative "the vibes of the speaker are generally off" type dismissals?
