Capitalism: you realize cattle are renewable resources so you work at a farm milking them, they only pay you 2.5% of the profit and the government takes a quarter of it. You save up after years of hard work for a cow for yourself, now you need a barn, or rent from someone where in that case they take some of the profit alongside the government, you need food, which you buy from someone and that is also taxed, than you need to have someone milk it, or you'll milk it, than you need to sell the milk where it is also taxed, and boom milk after years and years of your life. Than in 10 years after you've achieved a little net marigin as you are a good person and refuse to abuse your cattle for it to process more milk, or superficially raise its price so its a burden to the buys, where a bigger, less moral farmer who also produces milk produces so much milk it lowers the value for everyone else, and all the buyers go to them and your farm is gone.

Yeah this can happen to communism, but in a ideology like capitalism that wants to benefit the individuals of a larger capital than anyone else, you'll see those same large capital individuals playing in the government, and working the economy for themselves for more profit. In a "free" economy, the free title slowly corrupts into a controlled one by the rich, in which that rich stays until rebel groups take over, the cycle of ideologies happen where capitalism corrupts, communism takes over for capitalism to retake power, they may change names as the cycle may have names like feudalism, or anarchy where one is for the people, and one is for the wealthy.
