Michael Green and DD5 answered the question. I’m essentially saying the same thing, in slightly different terms.
A venture that makes a $1 million profit will require capital investment, a combination of equipment and working capital.
A return on investment will be required, else the capital investment would never have been made in the first place.
Perhaps a $10 million capital investment is required to generate this $1 million return.
If the tax rate is 50%, it no longer makes sense to invest in this venture at all! I believe that is the point Green and DD5 are making. Media pundits and politicians ignore the simple fact that capital is required in order to generate a profit. Since they think that profit results from worker exploitation, the income tax is justified and necessary. They fail to realize that profit is a signal, a signal that directs capital into the activities being demanded.
Also, these pundits who think the income tax is a good idea ignore the concept of WORKING CAPITAL. Growing businesses experience increases in accounts receivable and inventory. This creates a need FOR ADDITIONAL WORKING CAPITAL. Profit is a source of this additional working capital. A tax on the profit prevents this working capital form accumulating, thus strangling growth.
The business could borrow money, but this only increases leverage and the risk to the capital structure of the business. If anything goes wrong, there is no working capital cushion, and the business is in greater danger of going broke.
Analysts and commentators only look at the evil profit (the result of exploitation, noted above). They look at the “social benefits” that the venture supposedly takes from society (ie, law, defense, schools, traffic lights, clean air, etc.) and the tax on profit is therefore justified as a payment for these benefits. In reality, the venture benefits the consumers it serves, and in that sense it is society that benefits from the venture, not the other way around.
In summary, the tax on profit actually causes ventures: a) TO NEVER GET STARTED and b) STRAINS THE WORKING CAPITAL OF EXISTING VENTURES, restricting growth, employment, and raising the risk to capital structure of the business. This source of funding, which would have remained in the business or distributed to the owners for their own use and investment, is then squandered by government spending.
The income tax. Ugly situation, isn’t it?
