Explains a lot & yes you will need good hardware or a lot of mid-range hardware to mine. Nothing to stop you from investing in it though.

If you get your electricity for free than mining can be worth your time and $$$ otherwise unless the $/kwhr is super cheap it'll take a long time even to break even.

There are PLENTY of threads asking the same question, please search google, or look through the forums before asking.
