Sure you could find that on Wikipedia. Conservative opposition to the minimum wage is well known. They opposed it when it was enacted and now they oppose each and every attempt to increase it.
When Republicans were in power in USA for 12 years, they did not increase minimum wage even once (and of course, Americans experienced unparalleled prosperity for not increasing the minimum wage for 12 years, at least according to conservatives). When Democrats increased it, most Republicans voted against it. Mike Harris did not increase minimum wage here in Ontario for eight years that he was in power (and of course for not raising the minimum wage, Ontario experienced unparallel prosperity under Harris, according to Conservatives anyway).
McGuinty increased minimum wage when he came to power. Even in this forum, many conservatives (including yourself) are opposed to any increase in minimum wage, you would freeze it at the current level forever.
So yes, you could easily find it on Wikipedia. Or simply Google for ‘conservative’ and ‘minimum wage’ and you will find plenty of material describing the hostility by conservatives to the minimum wage for the poor, hostility towards the poor.
