Oh wow, Scroobal, I thought you would be the last person to take a deliberately misleading statement from a PAP minister and use it to attack an opposition party. The "same general level" refers to the so called monthly salary of $55,000. "Same structural features of fixed and variable bonuses (though in different proportions)" - These "different proportions" are what makes up all the differences between the WP's and the committee's proposal.
The final take home is NOT the same. This is very clear if you have actually read the transcripts of the debate.
Mr Yee Jenn Jong:
"Now, I would like to thank the Prime Minister for acknowledging that the Workers’ Party’s pay formula works out to be less than what the Committee has proposed. I believe Mr Vikram Nair and Mdm Halimah Yacob could check with the Prime Minister on how he arrived at the calculations. In our computation, the benchmark point annual salary for an entry level Minister with 13th-month bonus and an average 2.5 months bonus is $852,500, compared with $1.1 million as recommended by the Committee. This is a 46% cut from the 2010 annual pay. Furthermore, a portion of the bonus is deferred into a bonus bank. Under our proposal, the Prime Minister with the 13th month bonus and 2.5 months bonus will receive $1,534,500, compared with the recommended $2.2 million. This is a 50% cut from the 2010 annual pay."
