As far as I can tell, lower taxes would not have made my tractor purchase decision any different, because the last 2-3 years were income challenged in my activities.
Of course, profits are internalized, but all too often the costs of business are never borne by the business, nor for that matter the customers, and the prices customers pay are artificially low, and profits exceptionally high, as a result. If the true downstream costs of economic activity are actually brought into the cost of production, costs would go up. Is the cost of heart disease or diabetes captured in a Big Mac? It hasn't been. But when laws are designed to begin to mandate that these attributable costs accrue more to the producers, the change in economic relationships is fought tooth and nail. That is the battlefield we expect, and live in. But these changes are coming, whether we like them or not. And nations ahead of us taking steps to account for carbon production, to use one example, will be more efficient, and profitable with less wasted money, than those laggards like us who will maintain artificially skewed cost/profit relationships for decades to come.
In my opinion, only people are people, and legally constructed organizations of people, be they companies, or unions, or whatever, are not people and do not have constitutionally protected fundamental rights, period. They only get what benefits and rules we choose for them to have under law, but those benefits do not rise to "rights" the Founders intended. Our governing "watchmen" come and go, some certainly are crummy and some not, but most of them, while they are there, succumb to the money they need to raise and the interests behind the money. Election funding changes could lessen that narcotic.
As to home ownership, yes, price is a barrier that, if way high, prices folks out. My three young children will have to deal with that barrier, and others do now. Lawmakers, rightly sometimes and wrongly also, craft tax policies to make ownership more, or less, affordable and available to people. I was simply pointing out that the major parties we have today have had the expansion of ownership in their written platforms and as oft-repeated goals since practically forever. For some reason, politicians like home owners. And they like dangling that carrot to get votes.
I like owning my home, although the new roof I need this summer will like my wallet more than I want, I bet. No need to roll dice on that one, my wallet loses.
