>I mean, I'm not sure that your own examples don't disprove your point. McDonald's has plenty of competion - even within the fast food subset of restaurants. So does Coke. Even Google has a solid list of alternatives you can quickly find by using Google.

you realise that half those examples own the competition right? the companies that own coke also own some 50% of global beverages (the other global player being the owners of suntory).

all markets tend toward monopoly, its the entire inevitable end point of capitalistic growth. all wealthy people want more wealth and the easiest way to get it is not innovation or competition but bribery, nepotism and corruption. as a class they bribe gov (hence why its so slow and inefficient, its paid to be) to give them access to captive markets and grant them regulatory capture to crush actual competition.

wealth is less produced and grown and more gamified and almost purely speculative (massive growth in the most captive markets ie food, housing, healthcare, energy and gov keeps letting the wealthy have more and more of it because both sides work for the investment class)
