Why wait in this script is not executed after all subshells?

In this script, that pulls all git repositories:

#!/bin/bash

find / -type d -name .git 2>/dev/null | 
while read gitFolder; do
    if [[ $gitFolder == *"/Temp/"* ]]; then
        continue;
    fi
    if [[ $gitFolder == *"/Trash/"* ]]; then
        continue;
    fi
    if [[ $gitFolder == *"/opt/"* ]]; then
        continue;
    fi
    parent=$(dirname $gitFolder);
    echo "";
    echo $parent;
    (git -C $parent pull && echo "Got $parent") &
done 
wait
echo "Got all"

the wait does not wait for all git pull subshells. Why is it so and how can I fix it?
