Look around you. The entire economy is a giant money merry-go-round. Someone buys your product or service, you use that money to pay your suppliers, and you pay yourself what's left. You then go home and spend that money on food, gas, clothing, etc. Other businesses. They then take your money and pay their suppliers and pay themselves and their staff what money is left. And so it goes, around and around, in a giant money merry-go-round. And the faster that money goes around, the more chances you get to take a cut as it goes past. You may even end up spending some of the money you earned at a business that spent their money at your business, or vice versa.
Oh nooos, da gub'mint took mah moneyz!
Relax. The government will spend your money paying its suppliers, staff, and dog forbid some people less fortunate than ourselves, some of whom may even buy your product of service, and your money will just take a slightly different route around the same giant merry-go-round. Money doesn't magically disappear when you give it to poor people. They are so desperate they will spend that money almost immediately. And so that money keeps on moving.
Now, if you do the opposite, and enough businesses lay people off or outsource jobs to other countries, then more and more people will simply stop spending money. You can't spend what you don't have for very long. And if people are not spending, then businesses are not earning. The giant money merry-go-round stalls. Who will buy your product or service? Not people without jobs. The super rich already have 600 meter yachts and 787s, so good luck trying to sell whatever you have to them, especially while every other business is trying to do the same. Other businesses? Doubt it, they are trying to sell to you. And the people who still have jobs? They are struggling to supporting most of their family who got laid off by a ruthlessly efficient capitalist economy.
