SQL Server was in that range for many forms of licenses, and so was Windows Server when I worked at Microsoft. Actually I could think of a lot of software in that range.
Today, I was looking at UBS in South-East Asia..... A basic system may be a bit below $2k, but a functional system is probably about $4-5k.
Also a basic functional system of Sage ERP for smaller businesses is often well above $10k and below $50k
SQL Server was $50k per socket (going to core) for the Enterprise Edition as a list price. The typical SQL Server sale was >$100k, easily. Also, sales were negotiated and Microsoft licensing is totally fluid, especially if an Enterprise Agreement comes into the mix (where the cost is spread out over a few years). People citing MS licenses here are blind to how the majority of MS license in Enterprises get sold--huge deals with multi-year subscriptions that cost lots of money. MS will typically "true up" licenses at the end of an EA.
