Like a CPA? The problem is accounting is generally $150-200 hour rates so good steady income and good career but not great to establish a ton of wealth. Accounting firm maybe but it requires hiring people with degrees and careers which means heavy labor costs and thin margins.
Accounting isn't like other skilled labor like Attorneys and doctors where they can hire interns and assistants to do most of the work, Accounting typically has all the work handed to them by the business and they just need to review and rubber stamp it
