Consumerism is the idea that people like to consume material goods. This does not mean that they consume everything equally, mind, just that they consume and enjoy consuming. If people liked to consume without preference or limit then production-centric economies would maximise enjoyment and that would make people choose them over alternatives. Consumerism is not actually an economic system, it's just an assumption. I'd caution you guys to choose your terms carefully in future.
I believe you mean demand-side (or Keynesian) economics, as opposed to supply-side economics. This debate is still up the fucking air, I believe, and probably highly dependant on the current situation. I thought you were a marxist, with your talk of revolution and so on, why do you care about economics - isn't it the tool of the evil capitalists who oppose the workers' struggle to take control of the means of production and produce themselves into poverty?

No offense, but I think the confusion is partly on you. We're talking no mathematical facts here. Everything is an assumption. Even capitalism and globalisation, even though alot of people just take it at face value and treat it like a fact without really knowing what they talk about.
And even between the so called Experts (big 'E' for importance

I was not talking about demand-driven economics, but consumerism as part of a political/social agenda to fight socialism and keep the workforce at bay.
More in a tradition of Erich Fromm than Karl Marx or J.M. Keynes.
In the Shadowrun timeline/universe the corporations figured out, that guided (brand loyality) consumerism is their way to go. Whether we want to believe in it or not, the background sets it up this way.
So there we are, with lots of wageslaves instead of drones. And it is not because they drones could not do the jobs, it is because the big money wants people to work (or rot in the barrens) for some reason. What reason that is, we simply don't know.
Shadowrun does (like most sci-fi) make a choice on how mankind's future will look. The hard part is the short distance - suspension of disbelief can be a problem in alternate realities. It is easier to just go along Babylon5, StarWars or StarTrek without applying our current situation to it as it is far into the future while Shadowrun is just a few decades away.
