Yeah because in times anterior to capitalism, people didn't work, Science and technological research didn't exist, we were just a bunch of civilization-less beasts and it's all going to end with the collapsing of modern capitalism.

Of course you studied economics for two years and doing commerce in Uni, that's why you think you know something and you're convinced capitalism is the ultimate model, should have seen that.
Let me tell you this : Economics -as a science- is a projection that can only work on a closed economic model, meaning you're not being taught economics, you're being taught capitalism and how to perpetuate the actual model, without taking into consideration the social and political aspects. ... scholar programs are made by the government(s) so they're inherently political.

But I'll give you this, Capitalism had some good years and a bunch of technological discoveries happened under its reign (even though we can't be sure we wouldn't have had these under a different economic system, or maybe even better, who knows). But like any other system it's going to end ; it's corrupt, it's already eating people's rights away, and we already have he tools to go toward something better. In fact we're already slowly transitionning to "knowledge economy". Capitalism as you know it -material, seeking infinite growth with finite ressources- has become a drag for society, and a danger for mankind.
