The reason more work goes into multiplayer is because most people who buy the game play it. It's really popular and the majority likes it. The single player campaigns of The Halo/CoD series I found was really good and well done, quality over quantity. So really when you say they can't tell whether they play multiplayer, they actually can.
Your also saying that gamers are anti-social which is untrue and very stereotypical.
Also, maybe people want to play multiplayer and not singleplayer? your flawed argument works both ways.
What your actually saying is that game designers should go against what their target audience wants and make a better singleplayer for the minority.
It may be the same dozen environments but each and every game is completely different and has got much more variety than singleplayer. More interesting for the people playing.
Looks like your part of the louder minority.
