In other words, why do you think you'll never need to be supported through rough times? Our economy is rapidly changing - moving towards a knowledge based system. Outsourcing to third world countries is killing our manufacturing base and thanks to trade agreements, no one profits from that except the multinational corporations. Illegal immigrants fill the niche for unskilled labor. Few people have enough land or have sufficient water rights to produce their own food. And most middle class Americans are drowning in a sea of mortgage and credit card debt.
Tea Partiers are not at all opposed to safety nets. In fact, I am guessing that Tea Partiers give more blood, volunteer their time and talents in charitable organizations, and willingly give of their personal property/money at a much higher percentage than ANY other group.
In fact, I can't think of a single Tea Partier who does not believe and who is not willing to support a moral society caring for the truly helpless and those in need.
But Tea Partiers, more than any other group, know that no matter how well intended it might have originally been, the federal government providing the safety net is the most inefficient, ineffective, expensive, socially devastating, and promoting of corruption way to do that.
