Autism and AS does not carry a mandate to live in poverty.
The problem is that having autism or AS is a barrier to "normal" social interaction which is typically a key component to being "successful" or, at the very least, financially secure in life.
If you have Autism or AS....
1. Try building a "social network" by learning coping skills for the challenges posed by your condition and surround yourself with people who are understanding of your condition. These people will be your "networking" tool. It's certainly better than having nobody.
2. Focus on building skills and pursuing a line of work that minimizes need for social networking and interpersonal skills. Many with AS who do not seem obviously handicapped suffer failure after failure because they presume they are as "normal" as everyone else. Had they known otherwise, they would have made vocational choices that played to their strengths and minimized their weaknesses.
Good luck.
