I believe that moving from one country to another is the only way of voting that remains effective. As I don't believe in the power elections, over time, I found myself comfortable moving from one country to another with an understanding of the associated trade-offs. I believe every country will come to the understanding that people are the most precious resource. This rule comes as default in the corporate world driven by market competition, yet this wasn't really an issue for governments. For now, countries didn't fully grasp this paradigm, and therefore, migrating now is the best way to detach yourself from the state's system and look at the world as a diverse menu of countries to choose from. Before I continue with the menu metaphor, I'll get a bit more into why I think migration is almost a mandatory thing one can do.
First of all, by moving you control the change. For governments, time moves differently: months for a government are like days for humans. Therefore, in your already not so long life I don't feel like you should wait for the big changes but rather enact them (of course, if you need them). Your country is way too corrupt? Move to a more stable place. Living is too expensive? Downshift. Want less control from the state? There are loads of options for this matter as well.
Secondly, increasing personal independence. Migration builds up independence by detaching you from solid connections and opening you to a world of global-level opportunities (and are you really free without them?). The more you get into that, the more agile you get. This helps you set up a living where you count just on yourself.
Lastly, there are so many more practical bonuses in moving, including economic, academic, professional, and of course, you get to experience a new culture.
So, let's get back to the menu metaphor. Every country has its trade-offs that you will have to deal with and just find the one that suits you best. I will skip the obvious ones, like some countries are prosperous and have better salaries or higher taxes, and will get to some that I experienced on a more personal level.
Richer countries mean stability by any means. "Any" means that country will have higher control of the population, tighter economic restrictions, slower innovation embracement and in many cases, a poor culture (due to the professional "over-incentivisation"). Here is an example with Norway. It is an amazing country, where every single bank transaction is monitored. If you walk in a district you haven't been to before, more likely one of the neighbours will mention this to the police. The government controls your diet indirectly through taxation (which is twice as powerful in combination with market protectionism). At the same time, Norway is the cleanest country you will see, with amazing nature, unbelievably high salaries, beautiful landscapes, charming people and healthy eco-produced food (thanks to the food control by taxation).Freedom often comes with chaos. I have a strong belief, that in Russia you can kill anyone and get away with it, either by bribing someone (or just being good at hiding evidence). You can be loud there at any time of the day. Copyright doesn't exist there at all and nepotism opens even more doors. Not the best example of freedom but good luck being loud at 3AM in the German apartment. Don't think like an investor, think like a buyer. What I mean here is do not overthink about the prospects of a region. Do not try to guess whether the country will be on the rise in 50, 30 or even 15 years. Think "right now" with the max outlook of 5 years (10 at most). This is what you gonna get the most out of a single migration. The best thing that you can find is something with a positive current state and uprising economic trend (very rare these days).
