No no. Growth comes from taxation and tolls. Take Denmark. We raise the sugar toll so a glass of marmalade doubles. Resulting in the marmelade factory firing 200 workers.
Take the border shopping that climbs over 100% a year because danish wares are ridiculously taxed.
Take the massive amount of moonlighting going on in any sector able to make a buck out side the tax system.
To conclude. Growth comes from taxing the living shit out of common folks and businesses.
When it comes to the US or even the UK though, socialism is a pipe dream. We have too much population hogging our resources, a good amount of people who'd rather sit on their arse looking for handouts, and too many corrupt officials who'd exploit the system for their own gains. The only way it would ever work is on a state level, and only if that state limits the amount of people that come in.
Give me a small strip of land and a water source and I will survive. Not comfortably but I will survive.
Most of these people who starve in Africa do so in the regions in which food can be grown. It is a direct result of a fucked up tribal culture that seems to be dominant in the African society. Replace blacks with old-school hard working Germans in Africa and see if they would starve. I bet in a couple of decades they would be running successful post-industrial countries.
