He disclosed that the proletarians inevitably outnumber the capitalists. The capitalist mode of production is capable of yielding tremendous growth because the capitalist can reinvest profits in new technologies. But Marx argued that capitalism was subject to cycle of crises. Marx argued that capitalist society undergoes a continuous cycle boom followed by collapse with marked upheavals in between. He rightly pointed out that the net result of all this process is further strengthening and enforcement of bourgeoisie class and dilipidation of proletriats. Karl Marx assumed that if the proletariat class was to take control of means of production this class would probably indulge in social relations that would promote the benefits for everyone and thus making the society less prone to severe crisis. But this of course is more of an idealistic scenario where fairness and equal benefits for all are the name of the game, the reality on the contrary is quite different and the amicable solution of this problem is nearly impossible, and this shifting of authority from ruling class to common people would entail well orchestrated, large scale violent movement because naturally elite class weilding authority would no way be willing to let go without offering resistance. His theory advocates setting up of socialist system in which there is proletariat rule in placed and interests of proletariat are the deciding factors for establishing and implementing the policy. According to him this class struggle as mentioned in his "Critique of the Gotha Program," "between capitalist and communist society there lies the period of the revolutionary transformation of the one into the other. Corresponding to this is also a political transition period in which the state can be nothing but the revolutionary dictatorship of the proletariat." The wonderful aspect of his work is that he was cognizant of the significance of strong institutional structures that are the important assets of democracy. These institutions ensure that irrespective of the class inlinations and background...

These strong institutional structures could be seen in today's world in countries like the United States and Britain etc. At this point Marx agreed that the transformation could occur through peaceful means, and this might be the reason why these strong democratic countries are able to withstand jolts of social upheavals.
The Marx's idealogy definitely explain the phenomenon of mass movement to developed countries like America where millions of people flood to it from different countries and large proportion of them are residing illegally the reasons are far more detailed and complex then what the apparent common sense conveys, this generates an atmosphere of acrimony among local population but as mentioned by Marx this problem could be overcome by promoting democracy and strengthening institutions that serve the interests of merit and justice. The underlying message of Marx's ideology for this issue suggest that people opt for such countries because they provide security from the violent episodes that are part and parcel of capitalist environment's chain of events, hence this latent sense of security at the time of extreme uncertainty is an important criteria that attracts people to countries like America even if it involves living under the threat of strict immigration system. So for country like America that has set precedent in terms of strong democratic values and infrastructure this nemesis could be averted by projecting, promoting and encouraging need for democracy and consequent security through out the world.
