Its broke
The whole tax system is broken and needs to be reset for the modern world. We have some people being taxed into the ground to the point its almost not worth them getting a pay rise because it makes no difference to their bottom line. They just get more stress with little extra wage to compensate. They are stuck in a tax band with nowhere to go.. Then there are people and big companies that can avoid paying any tax at all. After all this the government still doesn't have enough money to pay for the services we need. System is broken.
