Why do people like boosters so much?

[Tooterfish]

I'm not asking rhetorically here, I'm genuinely curious as to why Boosters are considered to improve the game-play experience by so many people. I may be going out on a limb here in assuming as such, but I've rarely seen any real complaint toward it.

In my opinion, boosters only inhibit the overall experience. The grind, the well-deserved rank, the all around effort that is associated with leveling and progressing. I recognize the need to include appealing incentives for a premium membership or micro-transaction worth real cash, but how could shortening and ultimately devaluing your in-game status be rewarding to anybody? Psychologically speaking, it is reasonable to assume that a reward will be more meaningful when it is earned through hard work which, I might add, would seem more relatable, and appreciated, if achieved on an equal, un-tamperable scale (if that makes any sense at all). If all it took to become a millionaire was a few minutes of your time, then who would be impressed by a million bucks any more?

I'm probably looking at this all wrong, so I'm all ears here. Fix me please.
