Snow Shovels

There are any number of different kinds of snow shovels

Snow Pushers
Bent Handled Ergo Shovels
Wheeled Shovels
Folding Snow Shovels
Even Backpacking Snow Shovels

Why can't they just make one with a long straight handle. Regular snow shovels force
you to bend way down to pickup a load of snow, then straighten up to toss it, over and over again. People have been making long handled spades for ever for a simple reason, they are better. What's the disconnection here? I suppose I could McGuiver one up.
