The burden of tax lies more on the poor class in a regressive taxation system.

Regressive taxation refers to a tax system where the tax rate decreases as the taxable income increases. In other words, the proportion of income paid in taxes decreases as income increases. This type of taxation places a greater burden on lower-income individuals and families compared to higher-income individuals and families.

1. Definition of regressive taxation system:
- Regressive taxation is a system where the tax rate decreases as the taxable income increases.
- It means that individuals with lower incomes pay a higher percentage of their income in taxes compared to those with higher incomes.

2. How regressive taxation affects the poor class:
- In a regressive taxation system, the burden of tax falls disproportionately on the poor class.
- The poor class typically has a lower income and a higher proportion of their income is spent on basic necessities such as food, housing, and healthcare.
- Since regressive taxes do not take into account the ability to pay, the poor class ends up paying a larger portion of their income in taxes compared to the rich class.

3. Impact on the poor class:
- The poor class already struggles to meet their basic needs with limited income.
- When a regressive tax system is in place, it further reduces their disposable income, making it even more challenging for them to meet their daily expenses.
- The burden of tax can push the poor class deeper into poverty and exacerbate income inequality.

4. Inequality in a regressive taxation system:
- Regressive taxation systems contribute to income inequality as they benefit the rich class and place a heavier burden on the poor class.
- The rich class, with higher incomes, can afford to pay a smaller percentage of their income in taxes, allowing them to accumulate wealth at a faster rate.
- On the other hand, the poor class, with lower incomes, struggle to make ends meet and have limited opportunities for wealth accumulation.

5. Need for progressive taxation:
- To address the inequities caused by regressive taxation systems, many argue for the implementation of progressive taxation.
- Progressive taxation is a system where the tax rate increases as the taxable income increases.
- This ensures that those with higher incomes contribute a larger proportion of their income in taxes, reducing the burden on the poor class and promoting income redistribution.

In conclusion, in a regressive taxation system, the burden of tax falls more on the poor class. This system exacerbates income inequality and makes it more challenging for the poor class to meet their basic needs. Implementing a progressive taxation system can help address these inequities and promote a fairer distribution of the tax burden.
