How will the House and the Senate decisions affect the welfare of the US citizen?

Answer 1

I don't know precisely which House and Senate decisions you refer to, but generally speaking, you can count on most House and Senate decisions to adversely affect the welfare of the U.S. citizen while being of some benefit to 'big business', lobbyists, campaign contributors and members of the House and Senate.
Most legislation today stagnates growth in the economy; lowers taxes only for the wealthier segments of our society; further restricts citizens' rights and freedoms; causes higher consumer prices; creates a foolishly false 'trickle down' economy that floods the rich with more and leaves nothing but puddles for the poor. We live in a lop-sided, unfair, unbalanced republic, controlled by two corrupt political parties that interfere with our political system of choice by maintaining a monopoly on how that system is engaged for the benefit of the people. -RKO- 12/02/07

Answer 2

Higher taxes drain the economy, creates inflation, more unemployment and less deficit reduction. In other words they can have a very negative effect.
