Essentially, Obamacare would require firms to provide affordable health insurance if they have at least 50 full time employees or be forced to pay a fine of $2000-3000 per employee. Also, each citizen would be required to have health insurance, and subsidies would be provided to the ones that cannot afford it.
One view someone might have would be that this could cause the firms become devious. They could try to find a way to employ less than 50 full time workers and have many part time employees to avoid providing affordable health insurance to employees. Many people who desire or need to work full time many have to find multiple jobs, since firms would be reducing hours for each employee to make them part time workers.
If America were to provide health care through taxes, this would not be an issue. It is known that the majority of Americans are capitalists, which means they would be against government taxation, but the citizens of American also want universal health care. With Obamacare, America runs the risk of increasing unemployment, but if taxpayers provided health care, they could have jobs, and universal healthcare.
