This is not a story about bank bailouts but about job automation.
You vastly underestimate the need for demand. If all people in the US decided to cut their expenses in half and stuff their money into their mattresses today and do so for the next 5 years, the economy would shrink and a lot of people would lose their jobs. There wouldn't be enough money circulating in the economy to support all the jobs. Not bullshit artificial jobs created just so people would have something to do, but real ones. The economy would have the *potential* to do much more, but wouldn't because of the missing demand.
Automation of all low skill jobs has the potential to create a situation like described above - if a large percentage of population is replaced by automation, there will not be enough demand for the goods and services - even though the economy would have enough capacity to build and provide all the stuff (through automation), it could not sell all of it.
Sooner or later the helicopter drops will have to come.
