To add to what another poster said, it's not jealousy.
Big companies move slow because generally, to get big, they had to be successful (to some extent) and changing too much all at once is a risk that the bureaucracy isn't always comfortable with.
One of my old managers (I work in "enterprise") used to say things like "the efficiencies that this solution will bring the company..." which was just a euphemism for more folks getting laid-off (happened all the time, and glassdoor was full of warnings about this) or more jobs being shipped to our offshore units or even down-sizing in our offshore units.
I think it's reasonable, at least in the US, where healthcare & retirement & welfare is so tightly coupled with employment, for folks in big companies to be wary of innovation. They might want their job to be easier, sure, but too easy and they could be out of a job (for example, if the workload that previously took 5 people can now be managed by 2 or 3).
