First of all, you can't take them across greens, whereas the caddies can just walk across the green. There are so many people at tournaments, pulling them through crowds will not be very easy. And finally, the tees are so far back the players sometimes have to walk across things which are trolley could not go past.
It's based on a sliding scale. Most caddies get $1k per week plus expenses. On average, they get paid 10 percent if their player wins. . . .6% for top 5. .. . 4% thereafter.
They could do, and you do see it on some professional tours. The only reason you don't see it on the PGA and European tours is because there are so many spectators who make it logistically impossible.
Carts are only allowed on the cart path. If you have several lined up in a row parked to watch a player, their canopys would be a visual barrier to a lot of the foot traffic. So, for the same reason you don't want that guy in front of you in the movie theater wearing a 10 gallon cowboy hat, the carts have no canopys.
