Yea... I really believe one of the problems with our tax system is... not enough people are invested in it anymore.
When mean old W gave his "tax cut to the rich", my mother-in-law (who earned ~ $12k per year) was relieved from paying Federal tax at all. She had been paying ~ $1k per year. After Bush's Tax-cut-for-the-rich, she owed NONE. At the time, I was happy for her and thought it a good thing.
But, now.... I wonder if it wouldn't be better if EVERYONE paid SOMETHING. And, not just SS tax. Better that we all have a stake in the system.
