I think that on-demand customer service is perhaps the least stable sort of economy to be based on. The awkward on-call-but-cannot-be-doing-anything-else situation that many part time people are being forced into is not good for a stable economy. Those individuals will not have a stable level of income since it will wildly fluctuate with time nor will they necessarily even have a stable, consistent schedule. Without those two things how can someone possibly start planning for a future very well? In 20 years how is that level of stress and inability to prepare through consistency going to influence healthcare costs, retirement costs and overall efficiency?
A lack of stability like this is also detrimental to family life, children especially need stability in order to begin to grow and succeed in life. If their parents are constantly in-and-out with various part-time, on-call jobs trying to make ends meet, how can society expect them to provide that stability and support to help the child succeed?
It is just a question of what sort of future does this sort of situation produce, the benefits of simply having my ride, coffee and new pants on demand at whatever time I want does not seem like a fair trade for instability at all levels at all times. Yes, a certain level of instability is required to have mobility up and down but, it seems that this more extreme instability does not lead to more extreme mobility, simply more loss. Eventually, sure, a lot of these sorts of jobs will be taken up by robots/A.I. but, that still leaves the problem of what are those HUMAN BEINGS going to do without a job at all or an even more unstable version of it?
