Containers, along with other kinds of software-making tools for global-scale cloud systems, change the process of making software to a more automated system in which parts can be changed separately. Think of it as a change from an artisan working at a bench to a mass-production assembly line: Things are moved through faster and more uniformly. Putting this in economic terms, a lot more supply of computation is on the market, with an increasingly lower cost of production. As a rule, both of those things tend to keep down production prices, including wages. If it’s cheaper and easier to make software, why pay the same price to the people who make it?
