Either jealousy, or envy, not sure which you are at this point, Why does what other people do affect you, and how YOU choose to play here, no one is forcing anything, joining a guild is easy, and gearing is simple AFTER you put in a bit of work in the reg's and HC's on your first toon.
This part made me laugh, there is a very healthy population there, it isn't Icecrown's numbers, but more than enough to have a decent experience. which means you're on here to complain, or just lying about wanting play with people that earn the gear.
In any case, try using the search function, chances are there have been many complaint threads ( such as this one ) and could avoid posting repeated post topics.
