It might be argued that most of what is labelled as an "anticapitalist movement", sometimes self labelled as such, is not in the short term, nor even in the long term in many cases aiming for the complete abandonment or supercession of the key features of the capitalist system. To do this you would have to achieve the abolition of the wages system, supercession of the private ownership and control of the means of production, distribution and exchange and probably supercession of the modern nation state in its recognisable form. Most of the "anticapitalist movement" is not aiming at any of that anytime soon.
If "Another world is possible" there are a vast range of views on how and when! Many are justified in feeling that the most important things to consider in the short term are how to resist attacks or defend ourselves from further encroachments of amoral corporations
now.
The interesting question is of course the historical perspective. Looking at the current trajectory of capitalism in its most advanced sectors, then barring ecological/natural or financial disaster (which certainly cannot be ruled out and unfortunately look increasingly likely), the evolution of capital appears to be towards ever larger and more powerful corporations and consolidation of economic blocs on a global scale - i.e. the progressive destruction of economic activity outside the corporate framework except in a residual or parisitic form (think supermarkets, catering chains, offshored manufacturing, transnational domination of all sectors of the advanced economy - and corresponding disappearance of small shops, small farms, small manufacturers, "independent" nations or politicians, a vista of endless corporate shopping malls, industrial estates, leisure venues and ring roads.) Of course independent small producers and retailers may survive in pockets, but as "niche" marketing, often for the better off or self-consciously "alternative", not as a significant sector. As well as being strangely evocative of old marxist ideas about the evolution of capitalism towards forms that are virtually indistinguishable from state monopolies, the prospect is also of the shoehorning of all instincts - towards either independence and creativity
or altruism and solidarity - into the corporate monopoly. This equates to the "proletarianisation" of the bulk of the population in terms of their relationship to work, if not in their living standards - that "proletarian" working condition is ironically reflected in the OP's confession that he/she only works for the dosh!
We are reaching the point where the choice is stark - it now being
technically possible for the domination of corporate capital to become complete (virtually all media, legislative processes, community and nation state activities controlled at first or second hand.)
or the population decides a different route, a different route that will of necessity be based on different criteria of success and fulfillment to those of corporate capitalism.
For the real horror of the prospective future for most - if the trajectory is not checked - read the fatalist brutalism of someone like Ian Angell of the LSE. He argues persuasively that in the final version of the global e-economy the trajectory will be simply "uncheckable" by any of the traditional political methods, even were these not already under corporate domination. The global economy will simply
crush any opposition or alternatives, no matter how mild or unthreatening. Angell masochistically celebrates this, assuring himself that he will be on the right side of the fence when the techno-elite separate from the rest of us.
The question is perhaps not "what would you replace capitalism with?" but where the technological and social evolution of late capitalism will take us, and at what tipping points, crises or upheavals will alternative routes be possible. The historical location of these forks in the road will of course have a very great effect on what alternative systems
are viable.

That is of course (perhaps optimistically) assuming that the current evolution of the system leaves us with a habitable environment
