The fact is the farther away FIRST links are from your home page the less chance they have of delivering the appropriate internal juice and spidering they will need to get ranked. What I mean by FIRST links are first links spiders see of your lower level product/services pages.
So if you create this large website and FIRST link out to a product or service page 3-4-5 levels deep that page will probably have issues getting ranked, unless you have some solid internal cross linking going on to that page.
For instance let’s look at this in breadcrumb form to understand it. If I have a website directory of a car parts:
Jaan's Car Parts
Which is better
Jaan's Car Parts > Ford Truck Tail Lights
In this case we FIRST link from the home page to the specific Ford tail light page
or
Jaan's Car Parts > Trucks > Ford > Parts > Lights > Ford Truck Tail Lights
Where we now FIRST link to the Ford tail light page 4 levels deep!!
Obviously for the search engines option one is better, but it is simply not possible from a usability stand point. Look at this article:

Review the “
Optimized IA: Sections & Categories” section. The bottom line if the less links you have from the home page to the "money” pages the better off you are from user and spider stand point.
Now understand what is being suggested here has nothing to do with how many folder deep content is. Having content 7 folders deep can rank fine as long as your internal linking to the page is strong.
