The study found the median EROI for multistage second-generation biofuel systems ranges from 1.32:1 to 3.76:1.
That's not much of a return. To put it in practical terms, it would be like paying 25...75% of your wage just to have a job. The average EROI is reflected directly in prices because the economy runs on energy - all money is ultimately a token for energy because that's what makes things happen.
In the UK for example, a household is considered to be in energy (fuel) poverty if it has to spend more than 10% of its income to keep adequate heating and lighting. A society which spends more than a quarter of its economic resources just to maintain the energy infrastructure would be poor indeed.
