that wasnt so hard
but why will it be hard to pregram it is their job
Well, if you think a bit... which idea would you rather tackle:
1) build a car out of premade parts
2) build a car from sand, scrap metal, rubber trees, etc., creating your own smelter facility, etc., all from scratch
Just saying "it's your job" doesn't make a daunting task any more attractive, particularly if another option exists which is far easier, yet offers a similar result.
So... in the marketplace of suggestions for improving TW, if there are 2 ideas which both offer a roughly equal amount of, shall we say, "player attraction"... the one that is a lot easier to implement will very likely be the one they go for. After all, in a job, the idea is that you want to have a high profit ratio. Doing a much harder task for the same net result as an easier one is bad business.
