The Party-System should be beneficial to a Democracy; but, is it?

The Party-System should be beneficial to a Democracy. But, is that the case? Both Parties should have the general, common goal, of implementing Democracy; but, again, is that the case? Why is there so much 'strife' between the parties? If the goal is, generally, the same why should the 'way' to its accomplishment be so different and so 'competitive'. Of course, many party-candidates see 'politics' as a means of 'getting rich' and 'wallowing' in their own self-importance. But, there are 'underlying elements' that also affects the nature of democracy. Politics involves 'power' because its the only way to 'effect' the system as a whole. The power to represent millions is a tremendous power. That same power can re-shuffle democratic institutions to the point where Equality and Freedom are replaced by economic institutions, or simply by the 1%. In such a case, we are headed towards a Plutocracy. Some say we are already a Plutocracy; notice the dominance of candidates from the 'same families' or, 'group' of Party members. Its a cycle!, or 'bicycle' because it only has 2 wheels. That's why its so 'refreshing' to see a 'political candidate' that seems to have little to no political ambitions. But, beware! 'Money' could be replacing democracy! ( if it hasn't already done so) Nevertheless, the refreshing aspects of such a candidate is that he has breached a hole in all this so-called 'political correctness' of the Party System. Its a welcome 'insight' into 'political rigidity'. Lets face it; its not possible by someone, no matter how intelligent, from the Bottom of society. Lets wake up, human beings are not destined to go in circles. Our destiny can only be to help the 'helpless'. There's no other goal for a 'condition of togetherness'.
