Now that we are at last allowed to know a little more about the TPPA negotiated in our name, it is clear that the free trade goal that was said to be the main point of the exercise has not been achieved.
Tariff-free access for our dairy produce into US, Canadian and Japanese markets has been denied to us.
Such small gains as have been secured are so insignificant that Tim Groser, the Trade Minister, could not even remember what they were. The best he could come up with was a small reduction over time in the Japanese tariff on cheese.
The truth is that this much-touted goal was never even on the agenda. We were deluding ourselves - or our government was deluding us. The dairy industries of these large countries were too powerful and too protectionist to allow it to happen. New Zealand was just too small, too insignificant, to be taken into account. The negotiators knew, because we had made it clear, that we would take what we were given, even if it was virtually nothing - so much for "tough negotiation".
Even in those instances, such as kiwifruit and beef, where small gains were made, we - typically enough - put them in the shop window as net pluses, without taking account of the increased penetration of our own market across a wide range of other products.
So, if the TPPA is not from our viewpoint really about free trade, what is it about? As Joseph Stiglitz, the Nobel Prize-winning economist, maintains, it is about managed, not free, trade - and trade that is managed in the interests of large, international, and mainly US corporations.
There is of course a powerful case for an international agreement that would regulate the activities of international corporate investors across national boundaries. Such an agreement would ensure that overseas companies would - inter alia - comply with national law, would protect the interests of their workforces and would avoid damage to the environment.
But the TPPA is not such an agreement. Instead of defining the obligations of large foreign corporations in relation to the domestic economy, it tips the balance the other way. The TPPA is a blueprint for extending the operation of those corporations without their having to bother with the restrictions that might be placed on them by national governments in the interests of their domestic populations.
It represents, in other words, a further, large, and largely irreversible step towards the absorption of a small economy like New Zealand into a much larger economy - an economy that is increasingly directed from overseas, not by politicians or even officials, but by self-interested and unaccountable business leaders.
Perhaps the most obvious indication of that further shift in power is the Investor/State Dispute Resolution provisions included in the TPPA. These provisions allow overseas business interests to sue our government in specially constituted tribunals if they feel that the government has done or is likely to do something that might adversely affect their profits.
A democratically elected government carrying out its mandate, could - in other words - be compelled by a tribunal comprising just three unelected business people from overseas, to abandon its legislative programme and thereby give up a major power of self-government.
Much soothing language is at present being used to try to reassure people that there is nothing to fear on this score. Our own lunch-time TV news even reported - parroting the official line - that this power had never been used. That assertion had been dropped by the time we had got to the evening news.
The reality is that there have been hundreds of occasions where a power of this kind has been used - and that is to say nothing of those many more occasions where governments have been deterred from proceeding with their plans for fear of being hauled before a tribunal.
What the apologists fail to take into account is that we are now dealing with notoriously litigious American corporations who have demonstrated many times over their willingness to use or threaten this undemocratic weapon.
There is already the possibility that a mechanism will be set up in the US under which governments will be invited to obtain approval in advance from those corporations so as to avoid the danger that they will be forestalled later on - so that, in effect, overseas business interests will increasingly exercise a power of veto over what our government, and other national governments, want to do.
As we assess the impact on democracy and self-government of conceding these powers under a TPPA, we are entitled to judge the democratic credentials of those who have pushed the TPPA by what we have seen of it so far.
How can we have confidence in an arrangement that has been agreed in secret and over our heads, that has at the same time taken such care to consult and serve the interests of such a small group of powerful international business leaders, and that potentially has such a far-reaching impact on our ability to govern ourselves?
