In a capitalist system, especially one that inadequately regulates business, income taxes must do more than merely finance the costs of governance. Income taxes must serve a critical purpose in slowwwwing the redistribution of wealth into fewer hands over time.
Income becomes wealth over time. Those who earn more income become wealthier. Wealth accumulates in the hands of the most powerful. Money is power, and, as we all know from the Citizens United Supreme Court case, wealth is ‘free’ speech. This is not merely theoretical, but mathematically certain.
As the wealthy become wealthier, the richest people attain great LEVERAGE. For example, the increasing wealth gap was used in the early 00’s to stifle the computer revolution by purchasing the good works of the many people who made the internet what it is. Once the economy slowed, the excess wealth at the top consolidated more businesses. Competition vanished, consumer choices were reduced, quality went down, and, ultimately, real prices are climbing.
Excess wealth also went to buying legislation such as the 1996 Telecommunications Act that allowed fewer owners of media outlets. Then, of course, the actual purchase of radio stations, key internet portals, TV stations and whole networks, magaizines, book companies, record companies, etc., takes place. A smaller and smaller group of people control the information and the public becomes misled and confused.
Next, excess idle money in the hands of the rich becomes useful in wild market speculation, unlike anything seen before. Market bubbles bounce around in a casino-like environment, and many get ruined as the large amounts of money shift around from one thing to another.
Does any of this sound familiar to you?
Insufficient taxation of the highest income earners played a major role in where we are. Overall taxes in the US are down in recent years, and taxation of the wealthiest is down more.
