This is a good point. To add some colour to this. In my experience it's not that there's no money to spend. There's tonnes of money to spend, but there's also tonnes of people to spend it. The result is within the company you develop experts, people who know how to get access to the budget. Every year those experts spend a non-trivial amount of time making sure they get the company's budget. They spend tonnes of money, whilst the average employee never sees any cash in their entire tenure.

So in some ways it makes sense to make your enterprise price incredibly high - because the people within large companies will either be able to spend loads of money, or non at all. Very few will be anywhere in between (and will find it very difficult to pay or continue to pay over time).
