People and businesses earn incomes.  The money earned belongs to them.  A tax break allows people and business to keep more of what is rightfully theirs in the first place, and as such, is not welfare.  Welfare is money earned by others, taken from them, and distributed to others who did not earn it.  I know you lefties like to believe that everyone else's money belongs to you, but that sort of thinking is wrong and is in fact covetousness and greed.
Businessness provide jobs, jobs that allow more people, including the poor,to EARN their own money.  True corporate welfare involves government giving money taken from taxpayers to business; that I do NOT agree with.  But let's not pretend that a tax break is the same thing as corporate welfare.
Entitlement programs are well intentioned, but still doomed to fail, poorly run, and abused.
You leftists are always stuck in the "us versus them" mentality, losing focus on what you can accomplish if you try.  Victimhood is not a worthy objective.
