Why is my newish MacBook just so terrible?

I got a fresh, new early 2015 MacBook model in 2016 at an Apple store. $2,000+. Buying a computer for 2,000 dollars, I had high expectations. However, 1.5 years into my purchase, I’ve slowly started to regret it. I know MacBooks are not created for gaming and such, but being 2,000 dollar laptops, they kind of have to be good for gaming. (have a good graphics card and processor) But, NOPE. I am not sure what inside this laptop is worth $2,000. The specs are complete garbage, a computer with these same specs can go for a QUARTER of this price. Aside from gaming, everything else on my MacBook is sub-par as well. Having more than 7 apps open, the fan inside the laptop will start to sound like a jet plane. You can hear it from a room away. If I am playing MINECRAFT, for pete’s sake, the game known for not needing a good computer to play, only runs at max 100 fps with the fan sounding like a jet engine. My question here is: did I do anything to make my laptop as bad as it is? Or are MacBooks just made terribly and are complete scams and wastes of money? My bets are on the second one.

Thank you for anyone reading this, I had to get this off my chest.
