Getting a job where you can have success is difficult. I was first hired in sales/marketing and lasted only a few months before I was fired. I did then happen to get a government job. I was an import specialist with the US Customs Service. I was to apply the law classifying merchandise under the tariff schedule (what duty rates apply to particular products when imported.) I was also responsible for reviewing the value to see that it corresponded to reality. I actually saw very few people and just reviewed the filings, the import duty declaration presented with the importation, and compared it with other info available.
One story from a long time ago: The San Diego Museum of Art imported a cane with a handle carved by Paul Gauguin. Gauguin lived in Tahiti in the 1890s. The broker made a declaration declaring it a work of art and duty free. But... the statute excluded "articles of utility" from that classification and the duty on canes then was 20% - on the five or six figure price the museum paid for it! Much alarm followed. The free duty for "antiques" applies to thing over 100 years old, but this was the 1970s and the cane would have not reached that age. I continued research into the Tariff Schedules until I found a statute which was intended for Canadian totem poles but only addressed in general carved wooden art works which were more than 50 years old and were done "in the aboriginal style." These would be duty-free. You can research Gauguin's work while in Tahiti and see that he was working frequently with the style of the Tahitian artists. I determined, after doing this research, that it was over 50 years old and was "in the aboriginal style," saving the museum uncounted thousands. I did not do this as a favor but only because there was a statute, discovered after some research by me, that fit a duty-free classification.
To assess the proper Customs duty and classification was highly systematic and fit very well with my ASD world. If ASD people can find this kind of job which requires systematic effort and thinking it would help them succeed.
However, I did so well that I was being considered by management for even higher paying jobs, like supervising, etc. That's more money, of course, but requiring personal skills I recognized even at the time I was lacking.
