If Big Corp co is paying per man-hour doing a thing in a week that could be done in a day is actually huge win from the point of view of a business person.

Everything should be done as slow as possible as long as client isn't annoyed enough to change providers.

Business people both at your company and at Big Corp co customer benefit from keeping things as they are for as long as possible. They keep getting paid for as long as the project lasts. But when the project finishes, a lot can go wrong. It might turn out that it was completely unnecessary or that it doesn't solve the problem it was supposed to solve or that any given business person no longer has any utility for the respective companies. Basically a lot of trouble. So technical debt might be something business people actually silently treasure.
