This is an outgrowth of the democratic system.
Sure "parties" might start bright eyed and bushy tailed, pursuing ideological goals, pushing visions of social justice and the like; they all end up as brands.
They have a clientele or market and they sell power. The market is secondary; the primary focus is keeping power because that is their "good" for exchange.
It is almost a perfect reflection of the capitalist market (not free market); bureaucratic control, planning, marketing etc. It is, in the final analysis, a self interested corporation.
In the pursuit of power, what is more useful: money, ideas, vision? (the People? Lol )
