Corruption and Blackmoney in India

Corruption & Blackmoney are the two instruments more often and quite frequently synonymously used by indian politicians to earn and park illegal wealth. Although these topics are discussed at length in parliamnet and out of parliament numerous times, the country has been failed to eradicate this menace from the system and unfortunately this has been growing day by day since independence and today it reached a stage where it is threatining to derail the entire growth story of India.
It will not be wrong if any of us says "India is a country....where no works can be get done where the Government is involved without paying bribe".
Is it not possible to curb the Blackmoney: May not possible for Indian politicians since they are born and brought up in the same. However, I think its possible.

1). Curb the Physical cash holding: Impose a limit of around Rs.50,000/- as a maximum limit of cash holding by any individual at any point of time. If anybody holds above this limit,impose a life imprisionment.

2). Ban purchases and Sales in cash: Any purchase and sale of any commodities / items whose value is above Rs.5,000/-. should be transacted through Cheques / plastic money(Debit /credit card).
Impacts of above two steps:
1). Even if somebody accumulate blackmoney, he cannot use the same since any purchase /sale above Rs.5,000/- is not allowed in physical currency- So balckmoney tend to become waste and over period of time nobody intends to accumulate the same since the use is less due to above.
2).Since the cash holding limit is restricted -people will fear for holding excess cash and avoid using holding the same.

Requirements for the above:
As you are aware our politicians known to change the minds of people on matters which are favourable to them. For Example:-Income tax on agricultural Income. Most politicians in this country eavding taxes and parking their blackmoney earned through corruption as income from agricultural income. Although the legitamate purpose of exempting agricultural income is to help the farmers who earn seasonal agricultural income, the politicians are using this. Whenever anya ttempt is made to tax this worng side ...the politicians go back to farmers and try to raise emotional feelings with farmers....consequently many times the governements in the past backtracked fearing they may loose the farmers votes.
So in order to avoid similar scenario of agricultural income, the government /SBI should be mandated to open the Savings bank account for all the population of the country in a span of 5-6 months with minimum dposit amount(May be INR 100 /200).This may appear difficult task in theory to complete in 6 months...however most people in the country has the bank accounts. For children , they should get add -on cards linked to their parents accounts which will really help to track the parents income.
Once the above is done, whether it is a rent payment, purchase of car, payment to school fee, everything needs to be doen either though net-banking , debit /credit cards/ cheques. This bring compeltely accounted money in the country....at the end eradicate the blackmoney.
