The claim of the modern state is that it is god walking on earth and sovereign of all, with power to create fiat money and fiat laws. This philosophy is evidenced by the tax system. Inflation is thus a consequence of the state playing god and is of a religious origin. Inflation, by cheapening the value of money, robs creditors and rewards debtors. The state of course is the biggest debtor of all.
Inflation is the theft of the value of money and so the state is the leading thief.
It encourages thieves and favours debtors, for example, by allowing deductions for interest payments on debts but there is no benefit for savings, the interest received being taxed. However, inflation cannot work unless the state has a large number of allies among the people. They may be rich or poor, and in fact they do include both corporations and the poor. Everybody is out to get their special tax concessions or housing grants or subsidies or bounty. The hope is to get something for nothing.
