Will we ever stop burying people and start cremating everyone?

I want to be a mortician when I get older(I'm17)my dad owns a funeral home and I appreciate the work that is done with the bodies. I feel that it would take away from the experience of being a mortician when just cremating people all the time. Also when someone is cremated do they dress the body before burning it or do they just lay them in a box with no clothes and then burn the box?
