Money
We usually are paid at the end of the month. But not every month is the same. 28 x 12= 48 weeks. But there is 52 weeks in a full year.
So we are not paid for 4 weeks of work every year. A full month of pay. 😠

I don’t think it’s only money. The controllers obfuscated the model so that the people don’t understand the world around them. When you don’t know where you are it is easier to enslave you without realizing it.
