Nah, the only truly 'smart' dog to have is a gun dog and then, only in the country.
Black labs and springer spaniels will always be an upper-middle to upper class signifier and have been for decades. Of course, the truly smart have no need to signify their elevated status so you'll always have random outliers like mongrels and non gun dog breeds. Dogs have to come from breeders that the family have used and trusted for generations, or alternatively from a litter than some old family retainer has allowed their dog to have, in an ill-judged fashion. 
That doesn't prevent, of course, the parvenus and plebs like us from emulating the smart set and getting ourselves a (smelly) black lab or spaniel. I live in a semi-rural village so lots of people a bit lower down the demographic have got gun dogs and they give them a lovely life, lots of country walks and runs, etc. (probably no pheasant retrieval though, unless I really don't know my friends well.)
The current trend for Expensive Mongrels (eg. cockapoos, cavapoos etc) is just that, and regardless of family income has been embraced right across the board. I think it's criminal how much puppies have been going for, particularly this year, and it can only encourage bad breeders and puppy farms and imported animals from really dubious sources.
Having said that, I love a cockapoo and really enjoy the ones that (virtually) all my friends have got in the last couple of years!
