While they are a slightly more diverse generation, Gen Z have virtually no recollection of how bad the Bush years were (the oldest barely turning 9 when he left office) and have instead seen their parents struggle primarily in the Obama-led economy. Of course this can easily change if Trump or Pence end up being disasters from now til 2020/2024. Plus virtually none of them have entered college yet; which can shape one's worldview.
I'd say Democrats were, in a way, lucky to end up with Trump. Otherwise what we'd have is a deeply unpopular Clinton, completing at least 12 straight years of Democratic rule (wh), which has its perks but at the same it, it could drive a lot of newer young voters away from Democrats at least temporarily, if not permanently. These youngest voters, 18-24, would have grown up associating the country's problems with the person in the White House, as is usual, except this time you don't have a charismatic Obama to keep them from straying. Clinton probably would have sealed the deal on a lot of young voters who were growing skeptical of Democrats.
Instead, these youngest voters are likely to end up with a strong Bush-like effect for at least the 4 years Trump is president (if not longer). It took Bush years of terrible decisions and all kinds of highly negative events to generate that kind of negative imprinting, and Trump is doing it all by himself right out of the gate!
I agree with this though I don't see Trump lasting much longer. The GOP want Trump out and Mueller's investigation combined with Trump's frustrations with the confines of the federal bureaucracy will be enough for them to pressure Trump to resign. His entire twitter feed already reads like a teenage kid playing Call of Duty and is on the verge of rage quitting. Government is slow and sucks to work in unless you have a lot of patience; and Trump isn't a patient person.
