Title says it all. I'm in a country that has public health care, and in many aspects it is very good. Only downside is wait time. There's also less and less funding every year, less and less quality, the whole process to destroy and later privatize what is a natural monopoly (such as water, electricity, etc) and a basic necessity for human life and dignity, and so on.
With that said, is it wrong for me to benefit from what is essentially a better service (because of factors mentioned above, not because private = "better") because it is a capitalist enterprise? Same debate could arise from private energy companies, private transport providers, etc.
Adding to what others said: don't feel bad about surviving. If the capitalist state will not take care of you you have to do it yourself.
This is the same reason why I own stocks. Retirement is fucked in my country and things will probably only get worse so I invest in stocks. If the revolution comes before my retirement I won't need them so who cares what happens with them then? And if it doesn't I am still relatively safe during my twilight years.
Enduring capitalism doesn't make you capitalist so don't worry about it.
