There’s no such thing as a business that’s both lucrative and trivial. To the extent that you need finesse, hard work and luck to build a successful business, the same combination of finesse, hard work and luck could land you an equally or more lucrative corporate job.

You can also make passive income by investing your large corporate salary and earn extra income without working. There’s no such thing truly passive, zero labor income when running a business, there’s always some managerial overhead even if you delegate as much as possible. Index funds are truly 100% passive.
