I dont agree with the obamacare piece. How is it a redistribution of wealth? The taxes that are applied on the wealthy are small unless you are making a crap ton of money. For example, if you are making $300K you will pay between $75-100 in additional taxes because of obamacare. If you are making $5M+ its going to be more significantly obviously. The average household is making like $60K depending on location. You are talking about taxing the top 1%.
I agree with the individual mandate and the primary reason being that one of the biggest factors of spiraling costs in healthcare is all the individuals in the past that had no insurance. They would not pay, declare bankruptcy, etc that would result in hospitals/doctors absorbing costs and passing it to others.
What I do not agree with is the way that obamacare limits the market. People should be allowed to buy insurance that fits their budget and their needs. It currently forces you to buy a lot of stuff you may not want. They should have followed a system like Swizterland were you are pretty much forced to by catastrophic insurance and then add on whatever else you want. This way young/healthy folks and others have the ability to buy cheaper plans, versus the mess we have now where only sick people are buying insurance.
