I guess you never had to upload batches of pictures or home videos to family members on photo / video sharing sites, or heck even facebook.
Today's high res cameras output some pretty sizeable files.
I do, quite often in fact. Our EOS 5D MkII produces sizable files with its 25 megapixels, as do the other DSLR bodies we use in our studio.
But I doubt that people are uploading hundreds of RAW files from a $2500 camera. Most people are uploading JPEGs from small consumer cameras and smartphones and the last time I uploaded to facebook and photo printing services their app didn't take much time at all. I only have 5Mbps upload. I uploaded low res to print 5x7s and the prints from full, high res files were indistinguishable from those produced with low res uploads.
The average home user needs more download, as the average home user is more of a consumer of content rather than a producer. And with new compression technology even full HD video can be transmitted over low bandwidth connections with little degradation in quality.
