I believe that government has a role in our lives, don't misunderstand me. However, to take your points one by one:
Yes, government funds should be used to build infrastructure, including roads.
For Health Care, I believe in some funding, but I also believe that the health care system we have now is far from what Tommy Douglas had in mind. I have no problem at all with private health care, in fact, we have a lot of it now (dentist, eye doctors, physiotherapists, etc), that is covered in a lot of cases by private insurance. I believe that no one should be denied health care, but I also have serious problems with people using ambulances as private vehicles and emerg wards as doctors. To finish, our dogs and cats get quicker health care than we do. That is simply wrong.
I have no problem with private schools, why not? If someone works their ass off to make a lot of money to afford things like this, why not? There will always be a public school system, and unfortunately, the left wing bias of teachers is being passed down to our kids, whether on purpose, or by osmosis. Again, there should be choices, something I realize socialists and leftists despise.
Basically, what you are almost suggesting is that old joke about your tax return:
Line 1: what is your income?
Line 2: send it in.
As you may guess, I think that is not only not funny, but damned scary.
