Who is going to have their taxes increased?

The Obama-Biden  definition of those greedy people who have the audacity to earn so much that they must be taxed is rapidly shifting downward. 

Barack Obama initially promised he would tax
the upper 5% of wage earners, defined as those earning over $250,000.  But apparently that wasn't enough to satisfy his desire to spread other people's wealth around so in a campaign ad released a few days ago, tellingly titled Defining Moment, Obama makes a new promise, dropping the income for a tax cut.
I'll launch a rescue plan for the middle class that begins with a tax cut for 95 percent of working Americans.  If you have a job, pay taxes and make less than $200,000 a year, you'll get a tax cut.
Whoops!  Apparently thinking this is some type of perverse poker, in a Scranton, Pennsylvania television interview,Obama's running mate Joe Biden dropped the defining income of the wealthy to be taxed by yet another $50,000.  According to him, tax breaks
  should go to middle class people – people making under $150,000 a year.
But Joe, (I can call you that, can't I?) what about Obama's plan? 
And more importantly, what about the plans of the people who work for their $250,000 or $200,000 or $25,000 and want to spread their wealth around their way?
