As an empirical observation, in the US we currently have one group of politicians advocating for a larger safety net and a different group strongly advocating for lower taxes. Sometimes the bigger safety net people win, taxes go up, and payouts go up. Sometimes the lower taxes people win, taxes go down, and payouts shrink. Eventually these forces hit a stable equilibrium (or a semi-stable "pendulum") and the tax and benefit rates don't seem to explode or contract endlessly. I don't see any reason to expect that a basic income would be any different.
