The tax increase, IF your business brings in more than $ 250k profit(after all deductions, such as payroll and expenses, even a lot of your personal ones)- doesn't seem to me that big. Some individuals have lost a lot more in their 401ks in just one year thanks to greedy big business.
Obama's health plan would require large employers to put some money towards health insurance but on the contrary for small businesses like yours- it would create tax credit. I think it's fair to put some burden on large companies for the health care of their employees and I think businesses would profit from healthier employees.
