Regular tax amnesty schemes

According to a news item, Rana Sikandar-e-Azam Khan (President, FPCCI) has suggested that the government should announce repeated amnesty schemes to whiten black money . This shameless suggestion reminded me of what was said by PPP MPA Abdul Qayyum Jatoi: "Corruption is our right". If amnesty schemes become a regular feature, will it not encourage tax evasion and corruption? What about the salaried class, who pay taxes honestly? Why should they be discriminated against? In fact, why not abolish income tax completely? At least this will result in the government saving much needed revenue, which would otherwise be paid to income tax collectors.
