Jenny...the business Joereferred to is already in existence. That situation is far different than a start up. And that income bracket (which is NOT rich if you have a wife and couple of kids) is not as rare as you think:

If we start down this road of wealth transfer, you will get a wealthy transfer...the wealthy will leave, the historical way these issues have gone. The taxes are so high to hire anyone already, they will find other ways than hiring people.
I am now using secretarial substitutes and send some research overseas as the costs to access the research services are too high anyway (they try to bleed lawyers). If the taxes were not so high I would hire someone. But with the current high taxes and the sentiment in this country, I am looking more to find ways not to hire anybody. You will get more of this if Obama gets his way. Finally, the increased taxes will find their way to you and everyone else in the form of highr costs for services and goods. And the gtovernment will get more from you in hte form of the taxes on those goods and services. Nothing more than a Ponzi scheme and more restrictions on liberty and freedom.
