You wrote "huge costs that subsidies impose on us,". Care to explain how and why these are huge cost imposed on us?
Apparently big US corporations also pay "very little" in taxes.
Obviously this cannot come as a surprise, since it is the large corporations that have the ability to "lobby for" (contribute to campaigns to buy) these subsidies.
It is little different from the mercantile system, in which grants and special privileges were given to particular businesses in return for remuneration to the crown, which needed the proceeds to stay in power.
You don't appear to have a very good irony detector. Obviously I don't think it is a surprise. But it's good to have a solid handle on what the proportion is.
I certainly agree with you that large corporations are better able to lobby and I think that economic development officials probably have some bias towards large corporations because they can make for large job announcements. At the same time, there are subsidies for small firms (such as the Small Business Administration at the federal level, and various state programs as well), so it isn't a given that only big firms get subsidies. In other countries, there are much bigger programs for small companies than what we see in the United States. Austria and Finland are two I have heard of that have strong programs to develop small business, and the government of Quebec has quite a large program as well.
