Apparently the drivel espoused in the picture below is once again making the rounds. For some reason it never dies.
This is why such nonsense should never get the play it's receiving.
Suppose that you have a job where you are paid on commission on a daily basis. For every item you sell you earn, say, 10% of the sale price. Your customers buy from you on a consistent basis and you sell $2,000 worth of the good each day. Your total annual sales are $500,000 and your income is $200 per day, or $50,000 per year. (Assume no inflation for now and that you work 250 days each year.)
Your customers, who again, buy your good on a consistent basis every day and can't seem to get enough of it, think that you earn too much money, notwithstanding the fact that the benefits they receive from the good you sell far exceed your salary. Even still, they desire to punish you for your income and have all agreed to not purchase anything from you on April 15th. None of them have ceased consuming your good at all, only that they will not purchase anything from you on April 15th.
Let's say that in order to fulfill their demand for what they would normally have purchased on April 15th, half increase their daily purchase on April 14th, for total sales of $3,000 that day, and half on April 16th, for total sales of $3,000 that day. Your daily income looks like the following:
Without the boycott: April 14th = $200; April 15th = $200; and April 16th = $200. Total income over those three days is $600.
With the boycott: April 14th = $300; April 15th = $0; and April 16th = $300. Total income over those three days is $600.
Are you made worse off by your customers' decision to boycott you for one day? What if they did it for a week?
As long as they continue to consume the exact same amount, on which day or days they purchase your goods is largely irrelevant. Yes, it may be inconvenient that you don't have the income consistently, or that you might have to borrow on some days to tide you over until they come back to buy more of your good on the next day, but your average daily income has not changed.
In fact, I would argue that such ideas actually make the gas companies better off. If they knew for certain that nobody would be coming in to purchase gasoline that day, they could simply shut down, saving themselves labor costs and other costs or operation. Competition is what makes gasoline companies and retailers produce and sell every day. If they could collude in order to shut down one day with no cheating on the collusive agreement, gas companies and retailers are made better off at the expense of customers who want to purchase gasoline on that day. What a sham that the customers who appear angriest at the gas companies are the ones promoting the financial interests of the gas companies.
If you want to punish the gas companies, walk, ride a bike, don't go anywhere on that day and vow to not do what you would have done that day on a different day. In other words, as long as you continue to consume the same amount it doesn't matter on what day you buy it.
Actually, I agree with this. Everyone, buy all the gas you need for the next week today. DO NOT BUY ANY GASOLINE FOR THE NEXT WEEK. If you are successful and the price of gasoline plummets, thank you very much. I'll be filling up my cars one day during your boycott.
