Richard Rahn: The answer quite simply is that the tax increases are most often put on people trying to become rich, not those already rich. Hence, the rich, big government advocates can gain far more by "buying" the politicians. The "bought" politicians then provide them with confidential information about administrative decisions, which these donors then use to place big bets in the market, making themselves much richer. If you have deep financial pockets and inside information, you can make huge amounts of money when markets drop.
Mr. Soros, the Democrats' financial angel, is often referred to as the "man who broke the bank of England" in the 1992 Sterling crisis. During that episode, he made $1 billion in one day at the expense of British taxpayers. The relevant question is, did Mr. Soros bet a couple of billion dollars on mere guesses of what the German, French and British officials would do, or did he have inside information?
A member of the British Parliament, who was a close adviser to the British chancellor at the time, told me he believes "Soros was acting on insider information obtained from the French central bank and the German Bundesbank." The insider information was that they would not support the British pound, despite a pre-existing arrangement to do so. Others familiar with the situation have made similar charges.
Given that Mr. Soros is no fool, the British believe it is highly doubtful he would have made such a colossal bet without knowing with great certainty that the Germans would not reduce their interest rate.
It makes perfect sense: The more powerful government is, the more useful are the politicians you've bought.
