Bitcoin is not an actual physical coin, and if computers are shut down, you can't buy or sell them. That's why nothing will ever replace gold and silver coins themselves, and all investors should have them at home or in a safe deposit box.

Today's political leaders demonstrate their low opinion of the public with every social law they pass. They believe that, if given the right to chose, the citizenry will probably make the wrong choice. Legislators do not think any more in terms of persuading people; they feel the need to force their agenda on the public at the point of a bayonet and the barrel of a gun, in the name of the IRS, the SEC, the FDA, the DEA, the EPA, or a multitude of other ABCs of government authority.

Most of Marx's predictions have failed to materialize, and his labor theory of value and other ideas have been proven wrong. Marx failed to recognize the incentive system built into the capitalist model - consumer choice and the profit motive of the entrepreneur. The irony is that capitalism, not socialism or Marxism, that has liberated the worker from the chains of poverty, monopoly, war, and oppression, and has better achieved Marx's vision of a millennium of hope, peace, abundance, leisure, and aesthetic expression for the 'full' human being.

I find it ironic how New York City Mayor Mike Bloomberg is so focused on such small issues as drink sizes, while ignoring the massive infrastructure challenges in New York - lousy roads, third-world airports, traffic jams, etc.

The reality is that business and investment spending are the true leading indicators of the economy and the stock market. If you want to know where the stock market is headed, forget about consumer spending and retail sales figures. Look to business spending, price inflation, interest rates, and productivity gains.

The fundamental flaw in Social Security and Medicare is that they violate the 'welfare principle' in economics. The welfare principle forms the fundamental basis of all charitable work in churches and other private organizations: assist those who need help, and equally important, don't assist individuals who can take care of themselves.

We shall never change our political leaders until we change the people who elect them.
