### Comment:
Ugh don't make me rack my brains it has been too long.  However I know that R&amp;D also works alongside with the barrier to entry.  If everyone could just copy because you save money from R&amp;D cost then the profits wouldn't be as high.  Eventually it would not be as lucrative and less copy cats pop up.

### REPLY:
Profits will be reduced until the company bagholding the R&amp;D cost gets squeezed out of the market because they can’t compete with companies in a country whose citizens wear face masks because the air quality is the equivalent of smoking a pack a day while getting paid $3 an hour in a factory with suicide nets.
