Not to mention that they overlooked the fact that for some people - a sizable number too - the reward can be in helping others. Not everyone is a pariah looking to churn profits while pretending to care about other people’s needs.

Unfortunately the barrier to do this in capitalism is high, because like you mention, if you’re devoting your time to something that is not immediately producing profit then you may lose access to those basic needs. Companies can weather those losses, but will then want to make up the costs by - usually - using shady practices.

That’s not to say communism is the answer. But it surely isn’t capitalism as we have it today.
