If you're a solo-er or not someone who does WoE, you might still find a use for joining a guild on some of your characters. So I'll stress on the not-so-social aspects of guilds for now.
Most people usually join guilds mainly for the 50% Exp Tax (50% is the highest).
Exp tax only takes from your Base Exp and not from Job Exp.
What this means is that some characters can grind for job levels while easily holding back their base level (ex. A base lvl 100 Character with job lvl 22).
While not necessary, this method helps classes with builds that have leveling skills that need higher job levels to unlock.
Thanks to a recent update, guild storage is a notable benefit of joining/creating a guild too. But bear in mind that this is a shared storage and every player that is granted access can take whatever's in there. I recommend using guild storage for simple disposable stuff like supplies (ygg leaves, potions, and such).
As for the 'salary' or money-earning thing, those are mainly present in WoE guilds where the guild leader helps their members get their own supplies for woe fights.
Most of the guild functions like tax, title, and storage access are only changeable by the Guild Master. But these can be viewed and checked by normal guild members in the guild window.
If, however, you want to have one these options changed, politely asking the guild master to change it shouldn't be a big deal.
While guilds are mainly considered a social thing, it is entirely possible to make a personal guild that you can fill with your own alternate characters and still enjoy the full benefit of adding/removing tax and access to a storage that can be accessed on multiple accounts.
Personally, I'm active in 2 guilds:
1st = social guild with most of my in-game friends.
2nd = personal guild with private storage (which is also alternatively used as tax-only guild for my friends and I)(also for cool guild titles lol)
