That is not how it works, having a water cooler in the office increase the productivity 100x vs not having water, that does not mean you should pay millions for one. That is a myth invented by SAAS vendors and consultants to justify their sky-high price. The value offered of course factors in the price but many other factors too (scarcity of materials and resource to produce the good,cost of production, maintenance cost, cost of the products of your competitors, risk of vendor lock-in, etc)
