Some people get paid big money however if one believes one can simply start making memes and see the big bucks coming in that would be wrong.

However if you try to make money by making money there may be too much pressure and it may be bad for your creativity.
Just my thought. Memes can be a two edged sword and one needs to be careful how to use this powerful weapon/tool
