Final answer:
The controversies around Social Security focus on retirement age, income inequality, and federal tax rates.
Step-by-step explanation:
The controversies around Social Security focus on several questions. One of these questions is the Retirement Age - whether it should be increased, decreased, or remain the same. Another question is Income Inequality - whether the current distribution of benefits is fair and equitable. Additionally, Federal Tax Rates are also a topic of debate, as they determine how the program is funded. Universal Healthcare, while an important topic, is not directly related to Social Security controversies.
