If the interesting work all stays in the home country, how do you call that?

We like to kid ourselves that multinational companies are truly multinational, companies of the world. What's the percentage of non-American top managers, for example, working for American based multinationals? It's probably in the low 1-digit percentages.

There is a definite advantage to bejng an early investor. For these companies the risk is comparatively small and the rewards they reap are huge and on very long time horizons.

It's not super clear cut that it's all nationalist BS.

As far as returning the earnings to workers and local economy via taxes - yes there are expenses, you can't take 100% of income as profits, but there is a lot of leeway to direct the funds pretty much wherever the company chooses. Corporate headquarters in tax friendly countries are popular for a reason.

When the company buys in Romania and lays of the local marketing, sales departments, etc to make things more efficient, uniform and streamlined that doesn't help the local economy. That makes things more efficient tho but as a Romanian you're left holding the bag.

Now everything is foreign owned and the streamlining and competition has played out in such a fashion that there's potentially less competition and consequently less benefits off competition. (see all the modern industries that have turned into duopolies, monopsonies or the like that can easily keep new competition from coming in but also don't compete enough to drive consumer prices down.
