To me the most egregious is inheritance not being taxed like income. You can get $10m in a year and pay less tax than a working person.
In comparison to the majority of the population, you know the other 99%. That’s right, you heard it right. 99% of the population does not have $10 million free and clear without debt. In other words, if you are still paying off your house you are not in that upper bracket.
