It's worth noting that the breakeven rate is measuring what market participants are expecting the "official" inflation rate to be, as measured by the CPI-U. That may differ meaningfully from changes in the cost of living as experienced by the average American.

This is probably somewhat hyperbolic since companies who borrow anywhere in the ballpark of the risk-free rate (i.e., large, responsible, and generally financially conservative organizations) typically have an internal hurdle rate that is well in excess of their cost of capital.

What is true is that the hurdle rate exceeds the cost of capital mainly as a risk mitigation mechanism; it is a margin of safety. IRR projections almost invariably depend on certain assumptions about future business conditions. So artificially depressing the cost of capital can result in "more marginal" projects getting the green light, and therefore can increase the potential for financial damage in a serious recession. You can think of it as "risk leverage".
