Supposed to multiclass? Every class with significant spellcasting (Brd, Clr, Drd, Sor, Wiz) suffers if it multiclasses by losing spellcasting progression. Paladins can't multiclass and advance as a paladin. That's 6 out of 11 classes. Out of the other classes, the barbarian, monk, ranger and rogue all have a large number of higher level abilities that they slow down access to if they multiclass.
I'll go as far as to say you're dead wrong.
Quartz acknowledged the difficulties core spell casting classes have with multiclassing. He stated that non-pure spellcasting classes often gain almost as much as they lose when multiclassing (if the multiclass is well chosen so that weaknesses are covered by it), and even pure spell casting classes can benefit from two levels in a non-spell casting class (in bab, skill points, in feats, in class specials such as Evasion, etc - especially as an aid towards getting into PrCs that have otherwise difficult to meet requirements).
Personally, I cannot recall the last time I saw someone take a single (non pure spellcasting) class for more than 8-10 levels - let alone all 20 levels. I might see it more often in the future - now that PHB2 has made 10+ level fighters more viable with its variety of feats, but I have not seen it before and I doubt I'll see it any time soon. For pure casters there are too many PrCs that only sacrifice 0-2 levels of casting (thus continuing to allow 9th level casting at level 20). Then there are the many PrCs that act as patches for multiclassing - thus, in a sense, encouraging it. These allow for viable pure caster x pure caster multiclassing, pure caster x combative multiclassing, and other priorly less viable or non-viable combinations.
I think that 3.5e D&D at the least encourages taking PrCs (due to the dearth of interesting ones offered every other book it seems), and with the somewhat less numerous (relative to PrCs) core classes offered every fourth or fifth book it (to a somewhat less degree) encourages multiclassing or re-training into another class that might more closely match the player's concept of their character.
In fact, most DMs I know ignore both the multiclass penalty and the whole concept of 'favored class' as they see these as too restrictive compared to the number of core classes out there (about 60+ at last count) and the fact that some PrCs are not much different from core classes and yet offer no penalty no matter how many are taken. Sometimes these DMs give something to the Human and Half-Elf race for their loss (of favored class: any), but as often as not they do not (as all races benefit from the absolute lack of any multiclassing penalty - thus weakening the benefit gained from 'favored class: any').
As it is a common house rule in my area, I imagine it is likely common in other areas as well (much in the same way many DMs take a lazy or laisse fair stance towards encumbrance rules and how much can really fit in that backpack - so long as it is not
too outlandish (such as a ladder or ten foot pole in the (non-magical) back pack). Now I'm suddenly reminded of that scene in 'Mary Poppins' . . . .
