Instead of working your butt off by finding an AoB of a hack we already have (food is double *1), try finding something we DONT have... Like upgrades increase money instead of decreasing.
You can't give him crap about it if you've found absolutely nothing. Maybe he's just working on his AoB skills and was trying to find what seemed easiest. In any case, he can look for whatever he'd like, it's not like you have to use it. And also, your suggestion is just as useless since we havea money hack, all you have to do is freeze the variable.
