Nor have we tried. It is illogical to seek to prove a negative.
Have YOU established that raising the minimum wage would cause an across-the-board drop in profit margins for every corporation in America? That should be easy enough to prove.
It turns out that 43% of All Americans make less than $15/hour. Assuming an even distribution between 7.50 and 15, and assuming that we for no reason round this up to 50%, and assuming for no reason we assume that all of the 320 million people living in America are part of the work force, then that's 160 million people all getting a pay raise of $3.75 an hour.
$3.75 x 160 million x 40 x 52 = $1.2 trillion in new income for American workers.
Total corporate profits in FIRST QUARTER of 2017 = $1.567 trillion.
So even in this totally unrealistic nationwide minimum wage hike under the worst conditions imaginable, the result would be a 20% reduction in corporate profits in exchange for a 7% increase in GDP per capita. At the same time, the Median income for American workers would increase to about $72,000 per year.
Have you established that American corporations cannot survive a 20% decrease in profits?
Have you established that the increased demand for goods and services implied in a 7% increase in GDP -- and a 15% rise in median income -- is smaller than what is needed to balance the loss of revenue?
Have you established that the minimum wage increase would actually affect ALL industries and not just the ones whose employees make less than $15 an hour?
You're the one with the active position, you need to support it.
Actually, YOU are the one with the active position that raising the minimum wage would cause corporate profits to fall and therefore result in economic disaster. You don't get to demand everyone else prove you wrong when you haven't done anything to back it up except special pleading and generalizations. You can start by answering the questions above and showing your work while you're at it.
Showing that there is enough total profit in the business world doesn't show that there is enough profit in every industry, or in every business. The distribution is very uneven.
