In a free-market economy the dollar you spend had to be earned by someone; no matter how it came into your possession.
Assuming you live in the United States of America; the next time you walk into a store, any kind of store; stop for a moment and look around: Try to calculate the product inventory and then realize that all that value is money other people have acquired generally through hard work and speculation and there it is, waiting for you to purchase the products so all of them can divide your dollar into the massive amount of parts that it has to be fractionalized into in order for them to be paid for providing you with the opportunity to have what you consider necessities or niceties.
After you come up with an estimated figure try to estimate how many stores are in your State and then in the United states; all that inventory, which has been made available; waiting for you to purchase, so they can be repaid for their time and effort. Is this a fantastic country, or what?
One of the things that amazes people that first arrive here from a hard Socialist society (like Communism), is the availability of products and the fact that we have the choice of what and how much we are able or willing to buy at any given time; they have often had to wait in line to purchase products and with governmental oversight into when and how much and the further down that primrose path, called socialism any nation moves the longer the lines and the tighter the governmental oversight.
Now how does the dollar you pay the cashier in the store get divided? Think about all the processes it took to change whatever product you choose from raw material and put it in the attractive package that caught your eye before you bought it. This is long division that should be, but is not generally taught in school; partly because the schools have been directed toward a very subtle means of undermining the free market (capitalist) economy since the early years of the 20th Century; thus, below is an incomplete but I think eye-opening list of necessary payments from your dollar for goods and services, which you probably never thought of when the cashier put the dollar you just paid into the cash-register.
Retail costs: Employee ( pay and benefits), operations (insurance, utilities, trash removal, product climate control, building maintenance, heating and cooling), security, (manned and electronic) tax (income, sales, excise, local, county, state and federal)
And the massive cost of acquiring the products, which includes the costs of:
Manufacturing or raising and/or harvesting; plus research and development, packaging the product and sales costs.
Wholesale; storage and distribution including climate control, and security
Transportation: A consumer ready product usually has to be hauled from field, mine, or dock several times in different forms before you will see them in the store.. (most items are hauled by ship, train and/or truck at least five times; before the store)
This is by no means a complete list, but it touches on some things most people never consider; and two major expenses that touch all of them is the cost of advertising theft and breaking those down is a project I am not even going to attempt.
Freedom is not free it costs in time, thought, effort and often the courage to express and stand solidly for your convictions. Socialism claims to give you things, but the main thing is what it takes, which is individual liberty; isn't it amazing how slavery and socialism are so similar, although recognizing those similarities is not difficult if one looks without pre-conceived ideas and without fear of understanding. Beware of those who say profit is evil.
Government cannot give you anything that it has not taken (often stolen) from someone else and their claim of equality ultimately means equal poverty. Take it from the rich is their mantra, which does not include their wealth-control is the desirejust like slavery; we can win, only if we will fight it.
