If politicians get money to spend and don't have to be responsible for taxation, then of course that will bias their attitude toward more spending as opposed to cutting back on spending.

How would the US be different today if people coming off the boat were greeted with a welfare check instead of a shovel?

Politically, sometimes you get situations where rent control will go through. It is especially true in an emergency, where there is a sudden, sharp increase in demand for housing or a cut back in supply.

If you are going to spend for one group, you have to spend the same for every group, just like if you tax one group you have to tax everybody. You have to go back to having more general laws, more general taxes and more general spending programs.

Building on the public's unwillingness to act on principle in support of market solutions to apparent problems, whether real or imagined, these interest groups secure arbitrary restrictions on voluntary exchanges and, in the process, secure rents for their members while reducing both the liberties and economic well being of other members of the economic nexus, both domestically and internationally.

You have to have a government to provide you with legal order, with stability, enforcement of property rights, enforcement of contracts, definition of rules and regulations - the rules of the game, so to speak - and to provide certain shared goods and services, public services. Several people have tried to estimate this and they come out with figures like government spending at 15% of GDP. In the modern world it has gone to 40% or above. So we are way beyond the optimal, and that is easier to say than what the optimum is.
