It's really very simple.
Who manage's the people's money better?
The people who make the money or the government whom confiscates it and allocates it the way it sees fit?
Or as another member phrased it, who spends our money better? The government who prints it or the people who collect and hoard it?
Your question is reasonable and one that all patriots should think through carefully.
The other question is ad hominem is one that usually comes from the 'Statist' or "Political Class' mentality that the government technically owns everything and should allocate what the citizens should have or be allowed.
Using the Adam Smith explanation as expanded by Walter Williams in my previous post, 'collecting' is necessary in order for the people to look to their own security and 'hoarding' is what responsible people do to ensure that security. In more charitable language it is 'saving for a rainy day' or in Biblical language: it is setting up stores in preparation for the lean years that are certain to come.
As no goverment can possibly be smart enough, educated enough, or skilled enough to manage society or its resources as well as the people themselves will do simply living their lives, the more resources left with the people to do that, the better off the people will be. The government serves best by securing the people's unalienable rights and then leaving them to live their lives.
So then why have any government at all?
If governments serves no purpose, seriously, then why have it?
If you believe that governments are just nothing but wasted effort and the people will always know how to spend money more wisely than their governments then why aren't you an anarchist?
