As for inflation, it should still be, because without inflation, people will become lazy and do not want to grow anymore. Japan has suffered from deflation for many years and has made the country unable to develop as well
Very few people understand that
A manageable inflation (in single digits annually) is not really hurting the economy as long as it remains constant and predictable so businesses as well as households can reliably count it in. On the other hand, deflation, however small it might be, is very destructive on its own since businesses are straightaway discouraged from producing goods and providing services (as their profits depend on inflation/deflation rates non-linearly), while common people are in fact encouraged to postpone spending (hence the infamous
deflationary spiral)
