Yes, you can go to France and employ people easily provided you do not break any French laws, like not paying them enough. France has laws yet employers still discriminate based on things like your last name. For examples, if it doesn't sound French, you will not get a job.
Anyway, I don't know WTF you are talking about. You can go to France and start a business just like you can start a business in US.
Income taxes, and taxes in general are there to reduce monetary supply. Gov't, though the Fed, increase monetary supply. To make things balance and so *your* money retain value, there are taxes. Without taxes, USD would get railroaded.
Why should I work my ass off to make more money, and increase demand for employees, if I have to pay more taxes on what I make? That's robbing Peter to pay Paul.
Utter bullshit. It is called disposable income. If you earn $20k/year you will spend that money for local stuff because you have to live. If you earn $300k/year, you will not spend all of the money on necessities of life! You can afford to subsidize services that the $20k/year person uses.
And it is utter BULLSHIT to say that $20k/year works 15 times less than a $300k/year employee. By that definition, wouldn't the bankers earning $20m/year work 1000x times more than teh $20k/year concrete worker?
Your salary is not an absolute gauge of your input labor! The $20k/year concrete worker or a farmer that manager to just stay afloat may be working 1000x more than a $2 million a year trust funder, yet you would rather support that trust funder and kick the farmer and the concrete worker in the ass because they are not working enough for their services (ie. paying less taxes then services they get). Sorry mate. Rich people don't really care how much taxes they pay. Only the "I want to be rich too but I am not so I will blame government for it" people care.
