In its latest survey, the university found that the corruption index rose from 89.4 points in July to 91.4 points in August.
UTCC Vice-President Saowanee Thairungroj said 55 per cent of respondents said the corruption situation could worsen in the year to come if no serious action is taken.
Some 75 per cent of those surveyed said they would turn a blind eye to improper practices, saying it is none of their business.
Most respondents also think the Government is not sincere in addressing corruption problems. They suggest the Government foster good conscience in children as a long-term solution.
Meanwhile, the Anti-Corruption Network, which consists of 30 member organisations, is organising a major activity, which will take place on September 25 at Lumpini Park. The organiser is looking to invite Prime Minister Yingluck Shinawatra and Opposition leader Abhisit Vejjajiva to the event.
Chada Wattanasiritham, chairperson of the Thai Institute of Directors, said the event is held to commemorate the legacy of late ACN founder and former Chamber of Commerce Chairman Dusit Nontanakhon. She said the person who will succeed Dusit as ACN chairman has to work harder to encourage the private sector to fight against corruption.
Chada believes if business people and companies stop paying money under the table, it might prevent politicians from taking part in corruption. –TAN
