Is the "Law of Attraction (LA)" a really correct thing?

I agree that the LOA is a bit simplistic, to say the least. Psychologists call it magical thinking: believing that your thoughts create your reality. It's a simple way of blaming the poor for being poor, instead of creating a society in which there are less differences in wealth between the poor and the rich. Similarly: blaming the ill for being ill, instead of helping them get better or have a better life despite their illness.
