Isn't it my right to spend my hard earned (legal) money in legal way including making a HUGE house for me.....???
are we turning to communism again????

Nic, it's incorrect to say that so many billionaires come from extreme poor countries? majority of them come from developed countries and rest from developing countries (ref :forbes list of billinaires)
These (billinaires) are extra ordinary people with extra ordinary mind & skills, and IMHO, they have all right to spend the hard earned money in any legal way.......

now some people say these extra ordinary people should restrict themselves to level of ordinary people.......
This will reverse the evolution process of humankind.....
