Who is correct? I have read some Mises but no Piketty.

Their views reflect different philosophical and ideological perspectives on economics and society. What's correct is hard to say. The world is everchanging and complex. Best to read and give it some serious thoughts oneself.
Some of the statistics in the books by Piketty should be interesting. Some of his thoughts and words are scary. I live in a country where politicians are heavly influenced by his words!
