First of all, there are 2 certain things in this world, and those two alone: Death and Taxes. Even if the 1 billion is the net outcome, taxes have been paid. And taxes will be paid for everything you do with your money, even for saving it. Taxes are part of the economic waters that erode your mountains of wealth and fill your valleys of debt. So, what do I intend to do with 1 billion dollars? That is, of course, completely hypothetical, since I don’t buy lottery tickets. Kind of like the scotsman, who prays to win the lottery, but that’s not going to happen, because he doesn’t come half way. Well, I don’t pray for monetary blessings, since I don’t believe in any powers that would be willing to bestow said blessings. I just work for it. I digress.
So, if I found a winning lottery ticket in the hands of a deceased person without the possibility of finding their next of kin (yes, that’s what it would take me to gain such monetary blessing) worth 1 billion dollars, I would start a company. I would create a few thousand of job opportunities for people willing to fight for their luck. It would be a medical technology research facility, to further the cyberization of the human body, for artificial organs, limbs, neuro-enhancers and biointegrated com devices. Well, with 1 billion dollars (though I’d prefer Euros) and the currently all-time low interest rates, I could borrow another 100 billion dollars, hire the most renowned and talented bioengineers and provide them with the most advanced development tools available in the world. I would do it in Europe and claim Euro-funding worth another 50 billion Euros and further increase my credit limit with the banks to the GDP of Italy. I would also found my own health-insurance company, and put organ-transplant specialists on my payroll to implant my newly developed cyber-implants into their patients, thus securing my companies market share.
Then, phase II: creating my own empire of good. My own company enclave. My own laws, a completely engineered society. Get ready for a Brave New World!
