If it we're truly unlimited, I would set up a trust fund that would provide a stipend to every household living below the poverty level sufficient to raise them above the poverty level. Thereby eliminating poverty in our lifetime.

Yay me!!

Now, what if there were no hypothetical questions?

I've thought about this before. With unlimited supply of money, I would buy up all undeveloped land that is for sale and build nature parks there...winding paths, fruit trees, flower gardens, bee hives, ponds, water features, art, benches to sit and contemplate...maybe a swing or two, a see-saw...you get the picture. I'd employ people who were eco friendly to transform and maintain the properties, and pay them well, with benefits. I might hire someone to manage the logistics of all this while I travel. I love this fantasy!

I would buy my own country

There was an unlimited supply of money, it would be worthless. What gives it value is its scarcity.

Find ways to educate every girl on the planet to as high a standard as we can manage. That would radically reduce poverty, population growth, and general misery.

I wouldn't be able to because it would be worthless.

I'd donate a lot to the Freedom From Religion Foundation.

I'd probbgly only make some relatively modest changes to my lifestyle.

I'd see to it that everyone had decent health care and insurance. And for those that want it (not everyone does), a roof of some sort over their heads. Teachers would get paid so well, everyone would want to be one ! And all stray domestic animals would be neutered, sheltered, and readied for adoption ! Oh, and free pizza for all !

Get out of debt, get my financial life back on track, set aside a few million to use and generate income, give the excess to other slaves so they can attain some sort of freedom. No one needs billions.

Eradicating world poverty...wait the Vatican could do that and the UK royal family

I would immediately begin funding a method, or methods, to clean up our oceans and remove the trash, mostly plastic, from the sea. I would investigate the best way to get people off fossil fuels. And I would do what I can to ensure safe drinking water around the world. I would also try to get people interested in reforesting the places where all the trees have been cut down. These trees are the planet's lungs, and we need them badly.

I love you guys. We all had the same ideas. How cool is that?

Everything. FIRST take care of the homeless and hungry, then get rid of the evil administration since I will have more money than any of them-THEN pay for college for everyone, cure disease and get rid of big pharma and alopathic medicine, make medical care free for everyong THEN I'd indulge my whole family. There are only 9 of us, so that won't take long.

I've always felt that if I had more money than I "needed" (to live, including retire without worries) that I would quit work and distribute the rest to individuals and worthwhile charities. It would be more fun than work, just anonymously going around and easing suffering in the world.

Not working and taking my daughter to see all the museums and parks and zoos I can before they are gone- I want her to have a love for everything

I would pour money into education. All kinds of education: technical, trade, traditional academic... everywhere around the world.

Basic education to every mother in every poor nation.

The ways in which education could be supported directly and indirectly are immense. The end goal is to spread critical thinking and skepticism and humanist morality to the planet.

If it was unlimited I'd just pay for everything for everyone.

Doing whatever the hell I wanted.
That covers A LOT of ground.

To begin with, if the supply were truly unlimited or infinite then it would be worthless. But, let's just say it's a lot.
Money is like water, it's only valuable when it's flowing. Like irrigation, money must circulate and be distributed throughout the economy to be useful.
Building a dam and creating a lake is useful only for the purpose of controling it's circulation. Simply making the lake bigger without circulating it usefully is only wasteful.
If I had all that money I wouldn't do a few big things, I would do a lot of small things.

I'd buy everything and fix as many of the world's problems as humanly possible... Oh, wait, unlimited money has no value, so I would be broke as hell.

I would buy a congress. Not just a congressman or a senator, the entire Congress.

Well, let's assume that I couldn't use it to buy every country, company and person on the planet and rule as benevolent dictator....

I'd develop my own company, and use it to invest in developing countries by creating workplaces and thus employment. I'd probably also level out every country's budget, making sure that the debt crisis wouldn't get too much worse.

Let's see, what else... I'd probably do some more development work, helping along the agriculture sector of struggling countries.

Create a private army, to be a policing and stabilising force... hopefully not using it for conquest and dictatorship.

I'd pay for everything. I mean everything, everyone's cars, everyone's medical treatment, homes, holidays. I'd fund all proper scientific research, all space programs. I'd buy all the arms manufacturers out. I wouldn't pay for faith though.

I would not. Unlimited supply of money causes high inflation.
