Re: Career suicide
"Why does a society want to handicap the engine of the economy with income taxes?"
Because businesses use infrastructure and resources, benefiting from investments the rest of society make. This includes water, roads, refuse disposal; but it also includes healthy, educated workers. Public health services and education are some of the most important investments a society can make for its future. Businesses can choose to participate in society and its future by paying their fair share of tax. If they don't, they are parasites and should be treated as such.
If you want an example of why not everything can be a consumption tax, consider the Police:
"Officer, I've just been robbed. They took EVERYTHING!"
"Yes, Sir, I'll need to take the details, and the £10000 Investigation Tax"
"But they took EVERYTHING!!"
