1)In what ways do economists and political scientists use ethical systems and moral philosophy to evaluate poor economic and political policies?

2)If Trump's economic policies are destructive, why is the US economy so healthy?

1)The main features of ethical systems and moral philosophies are their coverage and their nature. The economists and political scientists evaluate economic and political policies by ascertaining whether those policies include all sections of the people in the society or not. They also ascertain whether those policies are socially acceptable or not. The policies should be such that they lead to social welfare in society.

2)

The reason as to why the US economy is so healthy despite Trump's economic policies being destructive is because it takes a minimum of two years for economic policies to take effect.

An example

Trump's economic policies can be explained using an example of a credit card.

Suppose one takes a credit card, maximizes it and spends $250 k over the next one year. That person's life will definitely appear to be pretty healthy, and people will say the person is doing good financially.

The narrative will change once the credit card bills' will have to be paid.

Trump has been borrowing finances from future generations. His economic policies give the impressions that the US economy is doing great. Nonetheless, his destructive economic policies will be revealed once the bills will be paid.

The US economy is so healthy as Trump inherited a decent economy, and put in place measures to increase the nation's gross domestic product with deficit spending.
