Nah. The point of the game is to . At the beginning money is of course useful, but once you pass the first hundred levels it's just sorta there for respeccing and nothing else.
Also, it'd take a long time for improved crafting to pay for itself. It's like 56k and it'll only save you about 10 grand on average per weapon mod. Skill points are a more valuable resource than anything in the game, just because they're limited while money is not. I can sit in a rats ovk and crank out 2 mil, but I can't get a few skillpoints from anything besides leveling up.
I don't completely blame anyone for taking it though. Technician has so much fucking filler, you either take improved crafting, the t1/t2 skills, or
