Can you explain what you mean by that last statement? It does not sound true to me. As far as I can tell (in my country) almost all consumer offers are asymmetric: ADSL, obviously, but also fiber. Symmetric offers are very much for professional access, and typically more expensive.
In Sweden, fiber (which is quite common) is pretty much always symmetric. 100/100 is common, many people have 1000/1000 and there is residential symmetric 10 Gb/s to be had. Asymmetric ADSL and Cable is definitely not uncommon though.
