Back to University or go and do other jobs ? Create their own companies and new services ? Why would they necessarily end up as homeless on the streets?
For the same reason they haven't already gone to school to get a better job than the one they currently have: they either don't have the money or the mental capability to do it. What makes you think this is going to change?
Erm... online education being now a thing, for one. Them having more resources now after having worked for x years than when they started without education. Them being probably married after a while and therefore having a safety net inside the family to be able to take some time off to learn new skills. Many things are plausible.
Wow, you have an incredibly naïve and rosy view of what life is like for the lower and working classes. Maybe you should try meeting some of them in person and seeing what their lives are really like instead of spouting this BS.
I come from a lower class family so im not sure why you assume i dont know what i am talking about.
You say that like anyone can just up and go back to university or simply create their own service (presumably some new, inventive one because the one they just had is already nearly perfected by machines). Neither of those things are especially easy to do with a decent paycheck, and these people wouldn't even have that.
Not just anyone, but the possibility is there. Stories of business owners who made it starting from nothing are not rare (obviously many fail as well) - but do not underestimate the resourcefulness of people who have their back against the wall.
The "let them eat cake" solution. If they had the opportunity to go back to university or create their own companies, wouldn't they have done so already?
