I'm tempted to not answer this, since you've flamed me already, but my reply might be useful for others.
I think autism is neutral more than wonderful. It's the defining aspect of who I am, and to cure autism would be to destroy me.
The reasons you've listed for disliking it aren't inherent to being autistic. They come from living in a society not designed for anyone except NTs, and from being surrounded by bigots.
Autism doesn't have to be isolating. If you're willing to get to know other autistics, we tend to be able to communicate with each other better than with NTs. Also, it's possible to get to know accepting, non-bigoted NTs. They're not all that plentiful, but they're around. Non-autistics are just as communicatively disabled as we are - they can't understand autistic body language, and tend to have trouble empathizing with us! It's just that there are more of them around for them to build social connections with.
The life experiences you're restricted from, I'm assuming are social, maybe romantic. I'm going to re-iterate the thing about being surrounded by bigots. If you've been unable to be hired for a job, hiring processes are not designed for autistics. If you've had trouble at a job, then that probably comes from the job not being structured in an autistic-friendly way.
It is possible to structure things to be more autistic-friendly, and hopefully it's possible to make people be less bigoted. Being autistic doesn't lead anyone to one specific point, but neither does being non-autistic. It's harder for us to be conventionally successful, but, if we find the right people and situations, we can find a job, develop friendships, and get into relationships, and be generally happy. (I don't mean to imply that there are certain things one must do in order to be happy though, it's certainly possible to be happy without fulfilling the expected life checklist.)
