When you operate a business should I feel guilty if selling price is more than purchase cost

[treasurekidd]

Several friends complained this is not right that they will only buy my stuff if I sell for exactly the inventory purchase cost of all inventory

They don’t sound like they’re very good friends at all.

You're selling pizza by the slice.

Let's say you buy an extra large pizza for $25.

Most people don't want to buy a whole pizza. They just want a slice.

It's plenty for them.

So instead of paying $25 for a whole pizza...

They'll buy just a slice from you, for $5/slice.

But there's 8 slices in your pizza...

So you've got a pizza worth $40 (8 slices x $5 each)...

That you bought for $25.

Make sense?
