> and so on is actually directly in your own self interest. But people have this idea that taxes benefit nobody so we work scrupulously to avoid them.
But my point is that it's not. It's in your interest to have those things but not in your interest to pay for them. Having government programs such as roads is beneficial. Paying for roads out of your own pocket is not. So we should expect to see people dodge taxes wherever it's practical to do so.
This has implications for how you design a taxation system. For example, there is an optimal sales tax rate that is neither significantly lower than your neighbors nor significantly higher—one where the inconvenience of shopping somewhere else is higher than the cost of shopping locally.
The only way to get around the problem is to make receiving the government services contingent on paying the tax. Vehicle registration fees are a good example, as are property taxes. If roads are paid for out of a tax that you can't avoid paying if you own a car, then using the government-provided infrastructure is contingent on paying for it and it's in your self interest to do so.
Sales taxes are particularly problematic in this regard because the people who pay them are often not the people who benefit from the programs paid for. (Though this is less true in small isolated towns than it is in large Metro areas.)
