One way I was personally affected by Obamacare:
Due to the Affordable Care Act, I can't work more than 29.5 hours a week or my company will be fined. Why? Because Obamacare states that all employees who work more than 29.5 hours MUST be offered health insurance, or the feds will fine your company. But seeing as how I have only worked here for (almost) two months and am still a lowly intern, I am still not eligible for health benefits through my company.
Synopsis: I was screwed out of better paychecks as a direct result of Obamacare.
