What is the difference between a public limited company and a charity?

A charity does not strive to make a profit and are very satisfied by their monthly deficit of money. On the other hand, a PLC (Public Limited Company) aims to make a profit in-order to sustain the business and generate profit. A PLC usually does this by selling shares of their company. The other difference is, a PLC will most likely buy their stock overseas in countries that are less developed in order to get a cheaper price due to their high-status, although, a chairty receives it's stocl by generous donations made by those who support the cause they help.

I hope this helps! :)
