If you’re trying to blame “stupid consumers” or “evil companies” you’re not thinking about things systemically. Of course, under our current economic system, companies are going to end up exploiting, because there’s lots of pressure to maximise profits, and minimal pressure to avoid decisions that make money but harm society. And consumers are going to make bad decisions, because they live in a society where they are constantly bombarded by advertising and social values that encourage spending and don’t punish buying unnecessary shit.
The naïve (or self-serving) status quo view is “but consumers should know what they can afford, and not waste money. And customers should take their business elsewhere if a company does bad things”. If that’s really what you want to happen, then create a system that incentivizes that - have strict rules on credit and loans, so that people can’t buy takeaway food on credit, enforce strict anti-monopoly measures so that there lots of genuine alternatives for consumers to turn to, have requirements for news media to inform the public about all the actions that companies take that are harmful to the environment, their workers, or the general population (and make clear who are their competitors, and only those alternatives that aren’t owned by the same conglomerate), and so on…
If someone promotes a system that relies on “personal responsibility” but doesn’t promote tools that facilitiate that responsibility, then they are being disingenuous.



Does population increase when famine hits? As I understand it the main brakes on population in human history have been famine and disease. The level of population that a society can support is usually based on its agriculture resources and technology. However, historically, the population would tend towards the highest level supportable, and then years with poor food producing conditions would cause famine and the population would contract.
Over the last century or so, the cycle has changed. Now societies with a food surplus don’t generally see constant population growth because of two things - food production is no longer dependant on how many humans can you put to work in the fields, so there’s less need for more kids to make a family’s work easier (in fact, each modern child costs more effort and expense than they produce); and we have birth control and education, which allow people to make more intentional decisions about when and if they have children.
Combining a lack of incentive with the capacity to choose means that many societies have broken the population growth and contraction (ie baby boom followed by famine) cycle. This leads to different problems such as aging populations, but that’s another discussion.
