Err, did they say that? I mean, as far as I know, equal CR just means it _might_ take someone out, not that it's a particularly deadly encounter.The real problem, however, is that the CR system is out of whack. A party should only expect to emerge victorious against an opponent with CR equal to their level 50% of the time, and should expect to suffer a few fatalities while doing so.
CR lets us know that a Flameskull shouldn't go up against 1st and 2nd level PCs cause their hp are too low (fireball - make a dex save die save for only dying). Ditto some dragons.
The overall XP budget is the bigger question. But yes, just like every edition of D&D, you can figure out ways to be more powerful than someone else. It doesn't even necessarily take feats or multiclassing.
