The system fills your mind with crap.

Keeps you busy with all kind of shit, from filling your taxes, to appointments, maintenance of unneeded things, waisting 8 hours a day doing useless things for a boss, travel time, watching propaganda on tv and God knows what more.

All to prevent you to start thinking for yourself.

Preventing you realize you're a slave.

Preventing you to find out what you need what makes you happy.

And most will defend that system.
