Yes, but for other practical reasons; regular paycheck deductions, including pre-tax deductions. I have no idea what plans are like elsewhere, but in the US a common plan is pre-tax deduction + company matching. So for instance, if your salary is $50,000 and you deduct 5% with a 3% match, then what you pay is:
$1,950
$50,000 gross salary x 5% = $2,500 salary deduction
$2,500 x 22% tax rate = $1,950 "take home pay"
What you get is: $4,000
Your 5% = $2,500
The matched 3% = $1,500
*your cost* = $1,950
And this is usually deducted per pay period. So you're effectively dollar cost averaging before you begin thinking about dollar cost averaging. But then you probably *should* buy simple indices, the lowest cost offerings available (Vanguard are the best, but many plans sell their own index funds).
So your rate of return is 105% *before* you see any market gains. This adds up *a lot*, especially over a long time. And only costs you $162/month (YMMV, as your salary may be more or less than these values).
