You can't be a sole owner and harness enough money to create a huge transnational business. And if you don't create a transnational business, someone else will - and sooner or later come to your own country and take away a huge share of your business, simply because he'll be able to race to the bottom of the market, while financing his business in other parts of the world.
This is what's happening with Kaspersky for example, who right now goes around the world, but urgently needs new money to push forward. Same with Yandex. In the modern world, unrestricted by national borders all that much, If you don't want to stagnate, you need to grow. To prevent Google from killing Yandex in the home field - Russia - Yandex needs itself to grow beyond Russian borders. And to grow, you need to constantly pump more and more money into business, thus every more or less big company requires IPO to take the fight for world share of its business to the new level.
What allowed 'capitalists' to survive previously, was difficulty to a) harness public money b) costs of transportation of goods worldwide c) more restricted national borders, absence of information, absence of sufficient economic/cultural exchange between countries
But I don't think, these two are connected: managerial government and the end of 'rule of capitalists'. The latter is merely caused by scientific revolution in the infrastracture, IT, transportation in XXth century
. The former though does seem to be the result of 'Roosevelt era', Keynesian politics, which in itself is 'managerial' by nature. Nobody believes in free markets since Roosevelt and it naturally leads to everincreasing role of the government first in economics, and as a consequence - everywhere. If you government can tell you what to do with your money, it is only a matter of time, before it starts telling you what to do with your life, your family, etc.
