Governments have always been extremely inefficient, they attempt to redistribute the wealth they get by the taxes they extort from the population, but a great deal of that wealth is consumed by them as they generate a significant amount of bureaucratic jobs which are unnecessary, give themselves high salaries and create useless institutions, so despite their supposed good intentions they end up not helping the people that need their help the most.
The difference between some nations is that taxes goes to waste in all kinds of nations, but some of them try to have less government, while others try to get rid of the corruption in the government.
I believe that we do need government and it's help, because there are too many things that can't be let to private companies, it just doesn't work better for the general population, but the way it is right now, our taxes are spent inefficiently so that doesn't work neither. Instead of getting rid of all those big budget governmental organizations, we should be getting rid of people in the government who doesn't use our money for us, but uses for themselves.
