> is that capitalism looks much like communism in the long run
Not sure what you mean here. In the long run, any communist country has ended up either being completely ruined (USSR, Venezuela, Cuba, North Korea) or turning back to capitalism (China, Viet Nam, East Europe). Surely capitalism's track record is not that sordid.

Companies also break up and whither away.
> because centralisation and control are the key for efficiency
Only for very narrow understanding of efficiency, taken as saving money on very mundane tasks. The same harsh reality of information flows that leads to socialist central planning end up in disaster in the long run applies to the capitalist conglomerates. Unless they are centralized only by name (as it is the case in holding companies, not exercising centralized operational control), they grow rigid, their technologies and business processes grow stale, and eventually they are beaten by young and hungry newcomers to the market.
The only way that they know to resist this process is to enshrine their way of doing business and their position in the market by coopting government regulation and raising entry barriers. That's why they spend so much money on lobbying - it is one of the most profitable investments known to mankind.

Not sure what that is about. Which company is that?
