The world is going towards global government, and there are almost no countries where Voluntaryism is widespread. More than likely, we're going towards a global welfare state. Here's the essential problem: overall societies prosper more with a welfare state. People are too selfish to provide for those in need willingly, so a welfare state is necessary to promote the efficiency necessary for societal prosperity.
The welfare state isn't a matter of right or wrong, it's a matter of efficiency. Even if the welfare state is wrong, it's the only rational choice for society. Unfortunate, this is the logical choice. Society doesn't care about equality or freedom, Society only cares about efficiency. Society doesn't care the individual, it only cares about the collective interests. the individual and the collective will always be inherently opposed
The only way to get rid of the welfare state, is to supplant society is the dominating model. That would require complete decentralization (aka self-managed anarchy)...However that kind of system requires active participation of at least a majority of the population, and currently, the majority of this generation is so irresponsible that they would prefer to have their decisions made for them by society, by culture, by government, by corporations, by advertisements on TV and the Internet
We live in a generation that is far too lazy to make any decisions for themselves, and this is why a collectivist society and government is inevitable. When people are unwilling to make decisions for themselves, a government and society to step in and control them in their own absence of willingness for self-control becomes a necessity.
Parents are currently so irresponsible they want the government to provide for their kid's education, their food, their jobs, their safety, their retirement, their insurance, their health, their lives. Everyone is depending on the government to take care of their kids for them. The government is so powerful because the majority of the people willingly gave the government that power because they are unwilling to take responsibility for their own lives.
