I consider myself to be an average Joe - never had one of those really high paying jobs or stock options, slowly progressed up the ladder to a mid-level position and saved when I could. In a year or two I'll retire and I'm pretty sure we will be able to live much the same as we have been for the past 40 years - decently, solidly middle class, not extravagently yet not in need of anything. All this on a middle of the road income, very little house trading (lived in same house for 27 years) and no keeping up with the neighbors.
Our kids went to public schools and colleges (for both bachelors and masters degrees). My DW and I went to "free" public colleges - meaning they were free to us, but someone else (the taxpayer) was footing the bill. I also earned graduate degrees through the munificence of the GI bill program (before they made soldiers put in their own money).
I've seen countless arguments in many places by people who don't want to pay for other's school, health, etc. The problem with that logic is that we all take advantage (or have the ability to) of taxpayer funded programs unless we are so rich we can fund everything ourselves. Taxes are the consequence of living in a free society. Right now our federal tax burden is the lowest it has been in a very long time. I certainly don't want to pay more for things I don't use, but fully understand the necessity of spreading the pain around. At one point or another, I believe most people have used some or many of the benefits available. I've been unemployed and received unemployment insurance. Our kids received federal college loans. And it goes on.
FWIW, we have lived in Europe (courtesy of the US Army) and there is nothing more that Europeans like to complain about than the high taxes. The VAT runs from 15% to 30% in most European countries - think about it - clothes that would cost 100 Euros cost 130 Euros with the VAT. Plus income taxes are pretty high in all those countries and downright confiscatory in some (Great Britain). If I am not mistaken, I believe the highest US tax bracket at one time in our not so distant past was as high as 90%. And now the highest marginal rate is something like 35% (?) - I don't know exactly as I've never hit that level.
Personally, the only reason I can imagine for becoming an expat would be if our country went down some insane road of internal (then external) genocide like Germany did in the 1930s. Nor can I picture events which would turn me so violently against our government that I would go "off the grid" and risk everything just to protest high taxes.
I don't know if brogan is a citizen, if he votes or what his income is. But I have not missed an election in 40 years (though some were done absentee) and I have no qualms at all about expressing my views to our elected representatives. That's the way our society works - I really do believe in the addage "I may not agree with what you say, but I will defend to the death your right to say it."
