I've worked in professional IT and know a lot of others who do as well. This happened because the more old commercial and industrial the company is, the less they know or care about spending on proper IT infrastructure, backups, stable and up to date software, etc. The worst of the worst of the worst is trucking companies, mechanics, etc. Second worst from what I hear is food manufacturers because of their margins. Third worst are American call centers. I know one that went through 3 CIOs in 3 years after their first one set up a fundamentally non-working, slow, dumb terminal shit show of a system.
The older the business segment and the worse the margins because of foreign competition, the crappier the IT infrastructure. So surprise surprise, a meat packing company got hit instead of a 10 year old medical insurance company. I'M SHOCKED.
