In the old days people would periodically lubricate the gears on their tools and appliances to keep them in good working order. In our so called “modernity” people have become too lazy and stupid to go around lubricating; so manufacturers have replaced hardened metal gears with plastic ones so that people don’t have to lubricate them. In fact in most modern tools and appliances, the way they are designed, you can barely access the gears let alone lubricate them. The downside is that plastic breaks a lot easier than hardened steel. Welcome to the throw away garbage life style. Here’s a thought: How many bottles and cans etc. do you have to recycle to make-up for all the damage that a throw-away appliance or tools is responsible for?
