Their economic model probably already includes taxes (would be stupid for a company of any size not to plan for taxes). Therefore paying taxes is part of their plan, and having them not pay taxes they are supposed to, only increases the profits for the top.
And for those that say they will hire more people, that is a total feel good argument. Companies hire people to make money off of them. They can pay you a wage such that the company has a monetary benefit greater then the wage they pay you. The point at which employees start costing too much, then they are reduced.
Your just proving everyone's argument, taxes go up, causing the cost of doing business to go up, people get laid off. Taxes go down, cost of doing business goes down, money gets reinvested in the company (if it's a smart company) people get hired, production increases, profits go up, etc, etc. It's been proven numerous times throughout history. It's nota feel good argument, it's a fact. Lower taxes help EVERYONE.
