There's no doubt that investment creates wealth, but let's remember that you subtracted $950 million of private sector investment when you took that money out of the economy in the first place. As you point out, the government needed to tax that $950 million. That means that those are dollars that private firms will no longer invest in innovation and capital acquisitions and other things.
Why do you think your department is better at investing other people's money than those people would be at investing it themselves?
