Its not some kind of reverse psychology. Having one bad employee can ruin years of work by a team to build trust and goodwill. Having to rebuild trust after someone burns an career executive because they were disgruntled about pay or working conditions can take years. If you know you are motivated by pay or working conditions then don't join, you won't be happy. This is the same thing I tell people who are thinking about joining a startup, if you are just in it for office perks go join Facebook, they have great BBQ.
