Yet most anime doesn't give you much pay off as only the main character is allowed to actually succeed at anything substantial except one off victories. Which wouldn't be too much of a problem but everyone else is always more interesting then the main character. They have emotional arcs other then "I get angry and win", plotlines, and they actually have to work at their successes. It is actually kind of odd because these animes will always paint the main character, who is given everything, as the underdog and yet really everyone else is for needing to face up against the unstoppable hero.
It is why often in some animes they give the ordinary hero who is good at everything (Standard fanfare). Then they give the "good but not too good" secondary hero who actually gets to improve and have arcs.
This can happen in reverse, in this case the secondary hero tends to be very smug about being the "clearly superior character" until defeated later.
Neon Genesis Evangelion, Code Geass, Full Metal Alchemist, Fate/Zero, Black Lagoon, Tengen Toppa Gurren Lagann (only because Stealth Protagonist, invalid later), Samurai Champloo, Mahou Shoujo Madoka Magica, Gunslinger Girl, SaiKano, Paranoia Agent, Death Note, Princess Mononoke, Spiral, Hajime no Ippo, Claymore, Kore wa Zombie desu ka?, Ergo Proxy, Digimon, Cowboy Bebop, and Shaman King (manga, because the anime probably ended in a silly way) would say otherwise, and most of those were taken to be distributed on US television (so they are some of the most popular series out there).
In each of those cases, either the protagonist doesn't always win, the protagonist experiences some very serious character development and isn't just given everything (or doesn't use that everything to its fullest extent), there are side/secondary or even tertiary characters that have their own very serious importance and character development, and/or the side characters are legitimately more powerful than the protagonist and either stay that way or most be overcome by serious development, etc.
I will agree that there's a good number of series that are just dumb like what you're complaining about, but you absolutely cannot make a blanket statement when a lot of the more famous series refute that. You're mostly talking about DB/DBZ, the Big Three, Fairy Tail, etc. which are all stupidly popular but they are by absolutely no means the standard of anime if we're talking about what gets adapted to the West, and by no means the standard of what is considered good anime, rather than popular anime, if we're talking about anime in general.
Also, if you're looking for comedy, look up Bakemonogatari.
