Memes of Production

The employees working at the company, collectively, have produced, maintained, and distributed the product. When the product sells, any profit (the money left after operational costs and reinvestment) was generated by that labor. It isn't all that complicated. That money, under capitalism, is siphoned off by a class that only exists to steal this surplus. I'm sure you'd counter with something about mutual funds and retirement accounts. However, this same class also steals from those dividends as well via fees and set percentages.

1. No because you made it yourself.
2. If a product is so wildly successful that your company makes massive profits, then the employees that made that product are entitled to that success as well. Why do executives, who usually don't have a hand in actually making the product, get so much more than the people who made it? Pay exists because there is no guarantee of profit on a product. Nobody will work for the promise of getting paid someday when promises don't put food on the table. Yes, a company should pocket a certain percentage to fund future projects and as a safety net, but everything left over needs to be divvied up across the entire company, not just the c-suite.
3. Reducing the price to stop making profit is fine since more people can afford to use the product. Assuming you hit a user cap, the price savings allow customers to spend that money elsewhere thereby increasing purchasing power. If you are selling to other companies, the other company now spends less meaning an increase in profit. This goes back to your customer's company spreading the savings back to its own employees.
