If it's time to shoot from the hip (or rather extrapolate), let's rebut a little bit.
i) Human working population is shrinking, but robots are rising. Remember this person doesn't exist

(but they look much like the real thing). See Boston Dynamics's Atlas, Spot etc. So, yeah, don't worry about demographics. Robots & robot assistants will multiply like rabbits (or rather like Windows 10 SW). This will overcompensate for the drop in working population.
2) Inequality is real. It's extremely dangerous and getting worse (tax cuts anyone?). But that doesn't mean it will reverse itself anytime soon. Most of humanity lived in bare subsistence levels vs the rich during majority of human history. If anything, equality is an aberration from the norm.
3) Access to information is awesome. This means governments & powers that be are hard at work stopping it :) Censure, regulation, control will be the norm going forward. Wild-west attitude towards information dissemination will reverse course.
(i) it's a very interesting point that you put forth. Yes, robots will compensate for the _working population_ ; However, I think the OP wants to direct the attention towards the economic impact of a changing demographic. Robots won't earn and [ borrow and ] spend. Consumption, Consumerism and the access to Capital is the reason world GDP has multiplied manifold in the last century and why it continues to grow. A shift in demographic has a massive impact on that.
I don't know about #2 or #3? Now that we've seen how good we can have it, Americans won't tolerate a Second Gilded Age for very long. Same goes for the massive, life-changing benefits of having easy access to any information.
