High prices are due to supply and demand. While ZIRP can cause high demand (and high supply of currency to fulfill that demand), the underlying demand still comes from the fact that software has near zero marginal cost, near zero liability, the ability to easily collect rent, AND high barriers to entry. The ideal business.
This means a business that sells software solutions can earn high profit margins, which is a necessary component to be able to then pay high prices to labor sellers. A buyer has to be both able and willing to pay a high price for the seller to be able to sell at a high price.
If the labor buyer is only earning 5% profit margin, then the labor seller is going to have a harder time extracting more money. But if a buyer is earning 20%+ margins, and their business is growing to boot, the buyer will be able and willing to part with more, hence higher prices for labor sellers.
