Yes and no...
As noted, compared to buying physical copies many are well worth the price. However, most of VC games could be easily emulated and are probably free on PC if you're willing to do the work to find them. Also it's nearly pure profit being made on VC games as there's virtually no production, distribution or marketing costs, where as WW titles have significant production and occasionally marketing costs (nothing compared to full retail but still) and they sell for about the same price which is ridiculous.
On the flip side, dropping VC prices would certainly hurt WW sales, heck, retail sales too, people only have so much time to play.
What I would like to see is Nintendo do some promotions with VC. Say, 1 free VC game with every 3 WW titles purchased (or could be 3 VC but let's help small developers out here), or a one time use code for a free copy of VC Super Metroid with the purchase of Metroid:Other M.
A promotional sale on VC games, well marketed to draw the casual audiences attention to it (and ww) could do wonders too. All VC games 1/2 price for one week, or certain titles on sale for a set period.
Steam has shown time and again a lot of money can be made from doing 1/2 price/80% off, sales on old games. Nintendo should take note.
