I believe that we need a few things for a nation to keep going stronger. We do not need some communist nation stuff where everyone has no possession but everyone lives a similar life, that is not the way to go, but more like European nations, well before all of this immigration situation started at least. You just need government to put some laws in order, and then get out of the deal, that's it, you put regulations and laws and everything in there, which will make sure that nobody goes poor, and all you need to do is make sure that the laws are followed that is all you need to do.
But instead, a lot of nations keep trying to take money from certain people and give it to another people, that is not how you get better, you get better when everyone lives happy without government control.
Few things seems not enough if we want to become or keep stronger but many things may be? I think communist nation do also has their own benefits? Because, it makes everything equal as you said and you know, many people nowadays are depressed when they think that someone is better or more wealthier than them.
I also/even think we don't really need a government but as long as people are already well disciplined, that should do the job and/but the more it can be attained when we are in a communist nation. I think a normal government or in a normal nation, can't control to make people not go poor, even if they strictly follow the government orders but this may be normal only.
