That is not true. Some tech people go in hoping to be millionaires, but the environment is extremely cut throat, esp with competition like India with billions of people keen on dominating tech, as well as Chinese skill. Many of the tech people end up competing to stay afloat, and to eat the weakest dog in the pack just to stay in that arena.

Silicon Valley and Seattle/Redmond are probably the most cut throat areas you could work in. It gets really nasty there.
