Today the term refers to someone who generally supports the social and economic status quo and is suspicious of efforts to introduce new political formulas and economic arrangements.

Conservative.

Explanation:

The term 'conservative' is used to denote 'someone who usually supports or favors the maintenance of status quo' and denies any kind of change or modification in the conventional institutions or beliefs. These people usually tend to show support, in fact rigidity to the 'social as well as economic status quo' and tend to show an opposition towards the introduction of any kind of new political arrangements or economic formulas that they view as a threat to their existing authority of beliefs/status quo. Therefore, such a person would be considered as 'conservative' in present context.
