The government we see are the economy themselves, when a bad government is on power then expect the economy to be in shackles. A good government implies a better economy same goes to when those holding power are faulty, everything begins to fail, inflation, cost of goods and services even for the one's manufactured locally inside the country.
Exactly. When a bad government comes in, the economy of that country becomes bad because they won’t care how the economy is going, whether it is favouring the poor or not; their own is just to fill their pocket and move on. Although some things will actually change whether the government is good or the other way, because some decisions only favour the poor and affect the rich, while the same decisions affect the rich, when it comes to things like this, seriously, you are right. It depends on the government that is ruling at that moment.
Governments' policies will attract or dispel investors, accordingly to its practical impacts over the investors' personal interests.
For an example, a government implementing harsh and abusive taxes will face a mass exit of investors from the country. The same is valid for dictatorships, where there isn't juridical stability, so investors feel fearful and uncertain about the next movements of the government and end cashing out their funds from the country to more friendly ones.
The government's decisions impact all of us in our daily lives and our daily choices also impact the government. The problem is that nowadays we don't work cooperatively anymore. The government treats the citizens unfriendly, and the citizens treat the government as an enemy.
That's why everything you want to do research on, you need to study it very well. As an investor, doing research is very important before investing in something; you need to make sure that what you are investing in won’t be something you will later regret.
However, taxes should not be the reason why an investor will withdraw his money from a country where he already invested, because even before the investment those taxes were there, so the investor should not only look at what the government is currently doing but also what the plan is in the future; that is what matters, not the current situation of a place, though it depends on the investment.
