I would say that the truly sharp take advantage of parlays for numerous reasons.
Here is just one of the reasons. If you look at a handicapper who consistently picks at a 53% clip, at -110 he has an expected value of 1.1818%. If that same capper would put 3 53% plays in a 3 team parlay paying 6-1 the expected value would be 4.2139%. That is a 256.6% increase over the expected value of the straight bet.
Here is a much simpler way to look at it, and you aren't using salesmen tactics by multiplying out small percenat into HUGE advantages to make it look like you are gaining something special.
I am not going to argue the math. But at 53% he has a theoretical success rate of hitting a winning parlay 14.887% of the time. So at a 6-1 payout, theoretically it is supposed to be profittable. I get a 3.58% advantage (Assuming you hit 53% every time) That is if you hit 148 parlays in 1000 plays you will profit $358 per $10 bet.
The thing is because the books are paying more than they should be you have a built in profit of $297 per $10 right there(6-1 instead of the 5.9579 they should). So by picking 53% rather than a needed break even rate of 52.4% (at -110, where you theoretically will hit 144 parlays) you are basically gaining $61 per $10 bet.
If you just hit the break even point of 52.4%, and do cash 144 parlays in 1000. Then you will make a grand total of $80 dollars profit.
So basically if you pick enough to break even straight( at -110). Betting parlays you will make a VERY modest profit(theoretcially). Simply because they are paying more than they really should.
But it is all theoretical.
