Conservatives claim that raising taxes on the rich will cause people to loose their jobs, but is this really what would happen
The rich who own companies or invest in companies make their money from the work employees do, they can't really make up for lost revenue from higher taxes by firing these people that make them money. If they have extra people working that aren't needed they could do this, but any good business does not hire people it doesn't need.
Lowering taxes on the middle class would create jobs though. Even though these people don't hire employees they spend money and this is how jobs are created. You could lower taxes on the rich all you want and it wouldn't create jobs, jobs are only created by consumers who purchase goods and services.
