First of all, with mojo bags, there are rarely profit to be
made. Items inside the bag and even the bag itself has to be
charged and consecrated. Not to mention some of the things in the
bag doesn't come cheap. Life isn't free, ya know? 
The correct term for the fee paid is called
"energy-exchange". A disbeliever you may be, but testimonies from
many others who have had the bags would swear at their results.
Then again, it depends on whether they appealed to a real pract or
some swindler for the bags.
Self-esteem is not symptomatic with luck. How many times have you
seen a wealthy businessman falls. You trying to say that all the
while successful, then suddenly lack self-esteem, one wrong
choice and... poof? I hardly think so. Bad luck is for real,
happens to everyone. One period, or more, of time when everything
seems to run dry in your life. The mojo bags for luck doesn't mean
you'll immediately strike 4D, though it could happen for a few
people, it just means that there's a cushion and things wouldn't be
as bad... Then again, if you choose not to believe... It's also up
to you.
All this is about faith, believing in the spirit. Although,
truthfully, I'm surprised that someone of your Age & Mentality
failed to see that... Sometimes, i really sympathise & wonder
if there really is a so called "Flawed Human Nature" or simply its
the way One is being brought up or there is a failure in the
Educational system. Warped Humanity is evident in our current time
& space, when people failed to see eye to eye with something or
issue , they simply distorted, assume & provoke to cause harm,
verbal insult or simply undermine something which they are in no
position to comment or challenge at all unless otherwise they are
REALLY "God form" in their own Name or an expertise in the
Metaphysic field...
You may be a christian, buddhist or whatnot. It still ends up in a
word- faith. Believing in the spirit. If you keep doubting it, not
likely to have much effect, is it? The believe system is different,
but the intent is the same. You pray for better life, do charity
for better karma. In our believes, we are more active, we work for
what we want. Sometimes, we extent our works to others. By
receiving an energy-exchange, our work is justified. Money,
services, products, reading, sometimes even deep friendship is a
valid form of energy-exchange... hope that while you follow your
belief system, do spare a thought for others with a life and
believes different from you...
