The economy of the last 8 years has benefited few at the expense of many. Furthermore, Republican tax policy is not as good aa it seems on the surface. Take health care for example. The last few years have seen a huge increase in uninsured people seeking care through emergency rooms at the expense of the public. This has led to sharp increases in health care costs and much of this is passed on to Americans through their health care premiums. I would take some universal healthcare and lowering of my healthcare costs in exchange for an increase in my taxes.
If you want to understand the culprit behind the enormous increase in health care costs, draw a graph of health care costs and government health care spending. Then run a linear regression analysis on the data points. You will see an alarming correlation. However well-intentioned, whenever the government gets involved in fixing a problem, the costs go up and quality goes down.
