Poverty which is caused by corruption. Only way to change the situation is to change people in government. But it's almost impossible.
I aggree, corruption is the source of all problems in our countrt. One major problem that exist because of it is poverty.
It is like which one came first, chicken or the egg. IMO, the root cause behind all these issues is over-population. It is directly responsible for the poverty and indirectly responsible for other troubles such as corruption and high crime rate.
