Exactly, I've been to a Vipassana meditation retreat, and the whole point is to eradicate suffering by eliminating feelings of craving and aversion. To see things as they are, without passing judgment. This creates a clear mind, free from worries and dwelling, and a more stable personality. From this comes happiness, as this is our natural state of mind.

People tend to mix up pleasure and happiness and think meditation provides the first.

Meditation, just like a psychedelic experience, can show you where you stand in life, and this can be scary. One can find out that they've been doing things wrong all their life, or realize that they are on a destructive path. The changes required might affect their spouse, children, friends or their job, creating a seemingly impossible dilemma, to go on and keep suffering, or to change and hurt others.
