Self-righteous, hypocritical comments from Harper's fan base noted. 

This is the system. Unless we want to move to a model that outlaws all private donations (i.e. taxpayer pays all party costs), then we accept the imperfections of the system we have. 

I agree that a $1500 or even $3000 donation is unlikely to influence ministers (although some companies have found ways around these restrictions). 

Bear in mind that there is nothing to stop large corporations from requesting a meeting with ministers on specific business issues involving government. The only difference is that there is normally a bureaucratic presence at such meetings. 

A private citizen or small business might not be met with the same consideration unless it relates to a high profile issue. Not sure there is any way around this. If Apple or Exxon approach government on a matter that involves thousands of jobs, they will inevitably get a faster response than someone looking to have his road paved.
