JAD,
if Dems got the exact same turnout in 2020 as they did in this election (ie, lower levels of minority support than 2008-2012, a significant WWC defection to Trump/GOP)...the demographic changes alone (both age and ethnicity) would have flipped the results.
the real question is "why wouldn't it?" IE, Bill Clinton reaped the political rewards of prosperity in 1996. for that matter, Obama was obviously doing decently if voters gave him another chance in 2012.
in any case, the Dem base, or more accurately coalition, has never focused solely on economic concerns. (for that matter, the entire electorate, and -especially- Trump voters; the single biggest predictor of whether or not a person was going to vote for Trump was NOT socio-economic status or even party affiliation (!) but their answer to the question 'Do you think Barack Obama is a Muslim?').
i think you're mistaking the black swan event for a trend (and i mentioned this before in a different context-- whether or not a Trump administration actually constitutes what conservatives would consider...conservatism).
to look at it from more of a generational view, Baby Boomers and the remnants of the Silent Generation came out in higher numbers, and they voted decisively in favor of Trump. Millennials, having grown from 19% of the electorate to roughly 30% of the electorate today (matching Baby Boomers in size, although actual turnout was rather lower to HRC's disappointment), have voted decisively Democratic in every single election since they became eligible to vote. by 2020 they will make up 35% of the electorate, and by 2024, 40%. their views are significantly more liberal than their predecessors, which GVChamp has noted to his great displeasure, lol.
there is some indication that the post-Millennial generation is slightly less liberal than their Millennial counterparts (they grew up in the Obama years, not the Bush years), but given the absolute size of the Millennial cohort (even bigger than the Boomers!) they will not reach parity until roughly 2060. of course predicting politics that far ahead is a fool's game anyway.
By 'medium-term demographic' may I assume you mean the continued increase in the Hispanic population (and other ethnic groups). If so, the dems have some hurdles to get over. First, the majority of Hispanics would have to affiliate with the Democratic party. Second, the party would have to retain its traditional base (no significant defections to the right). And third, the Republican party's current hold on the White House and the Congress would have to yield poor economic results.
As for the Democratic base, why would it hold together if the economic situation improves in the intervening years. What could the dem leadership offer them?

That is not to say a Democrat can't still win the White House even as the flow continues rightward. The GOP did it periodically after the progressive movement began with FDR in the 1930s; yet, despite those interludes, the progressive movement kept its momentum intact. Even now I'm not altogether certain it has lost it, but it seems so. We'll see.
