A couple of potential systems might involve subsidies and time-based temporary protections (similar to iframes in games) to incentivize the build up of domestic competitors.

Implementing a system that incentivizes the constant import of foreign goods and services would be the replication of Hong Kong's mistake(before they got taken over by China and the CCP):

• De-industrialization was Hong Kong’s Biggest Mistake

Increasing dependancy of external systems means the reduction of self-autonomy and independance especially when it comes to critical infrastructure such as internet and technology.

I see this as a fine balancing act as you don't want to always depend on externalities but at the same time, the fear of foreign goods is a major cause for concern as it plays a part in the increase of racism and extreemism, while also destablizing the bridges of trust you have with others (which is def bad as you'd be placing your eggs all in one basket) cause you to become more susceptible to bad actors.

These complex systems makes me hesistant in the reckless recommendation in opening domestic markets to foreign competitors without further analysis as you don't want untrustworthy entities from coming in as it would only perpetuate a winner-takes-all system thereby leading to an eventual collapse of the market with a monopoly at the end.

At the same time echo chambers are just as toxic and leads to monopolistic systems. And this is why the real solution is the dedicated research to find a balance in which I am not the top analyst to speak on.

TL;DR:
shit's complicated because of the systems involved, the best solution will come from researching further

Whatever they're doing (or not doing?) now seems to be working. We may be paying more than other countries but I can say my phone bill is lower than it's ever been since the beginning of the smartphone age and I'm getting way more for those dollars too.

Edit: that being said, I do hear of people paying close to $100 for a phone plan. I don't know how they just go along with that or what value they think they're getting but it's definitely not necessary to spend that much these days.
